why and how we reproduce?

HOW WE REPRODUCE: the male reproductive system and the female reproductive system are necessary to create a new live. The male introduce 300 or 400 millions of sperms, the one which swims in the uterus, with a time of 1 or 2 hours and then the sperm enters in the ovule, fertilizing it, that process that is called zygote, like that is formed the baby,  taking in to a count a development of organs, body , brain in nine months.
WHY WE REPRODUCE: the life cycle is something necessary to create a new life ,that lives for generation and generation and the person do the same, for human being never be extinct other species do the same, like animals and some plants. There is other form to make a new life, is called asexual reproduction, the sea horse can reproduce when is not necessary to have a partner also it can clone.

How and why humans reproduce


The human reproduction is by sexual reproduction the man have the spermatosoids in somenting that is named semen the, semen is contain in the testicles, in an man and wemen intercourse they use the reproductive for create new live the man introduce the semen in the wemen to they for go to the ovary And create like a egg that create the baby and it grows and it have the size and it is sufficintly developed to survive on its own they born.
The humans reproduce because they need to perpetuate the species named human or (homosapiens).
Abort to me is something horrible because create a new live is a very good expirience, the only ones that abort are the ones who don't have with what give a good live to they but steel be bad to abort, I think other think is that they are nervous because they don't know what the parents are going to say or the father what is going to say because a wemen in that moment don't know what to do because I imagine they have a lot of depression because is a notice very surprise.

Texto Argumentativo

Texto argumentativo de la superpoblación en los humanos, plantas y animales:

Yo estoy a favor de la superpoblación en las plantas y animales por que esto puede llegar a perpetuar siertas especies que ya se van a extinguir, puede haber mas biodiversidad de plantas y animales, podemos disfrutar mas estas especies, además su ciclo de vida ya no sera interrumpido por los humanos y las especies pueden tener su propia vida.

Y estoy en contra de la superpoblacion en los humanos por que ahora el problema es ¿Que pasara si la superpoblación sigue aumentando en los humanos? Esta es una pregunta muy difícil de responder pero creo que hay una solución y es educar a los adolescentes o niños sobre la reproducción sexual porque esto es lo que mas se ve hoy en día en los adolescentes, que ellos no tienen la edad suficiente para tener o cuidar a un hijo, por eso se estresan y esto puede llegar al tema del aborto. (embarazo no deseado). El aborto tambien lo pueden causar los problemas familiares.

La superpoblación no solo lo causa el embarazo no deseado, también lo causa la reproducción en exceso por que hay muchas familias que tienen mas de 7 u 8 hijos y no tienen lo suficientes recursos para poderlos mantener ya que esto causa que destruyamos los habitats de otras especies y la extinción de especies.

Si la superpoblación sigue creciendo en China o en India que pasara? Yo creo que van a construir otro territorio para que los países que tengan superpoblación por ejemplo en China o en India es que el 50% de las personas se pasen a vivir ahí para que quede equilibrado el porcentaje de personas que viven ahí. O que se pasen a vivir a otro país que no tenga el problema de la superpoblación.

Además que nosotros dependemos de la naturaleza y los animales por que si los animales ya no tienen de donde comer entonces ellos se van a extinguir y ya no habrá alimento para los humanos y nos morimos osea que todo nuestro ciclo de vida va a terminar por culpa de los humanos quien estamos talando arboles usandolos para hacer cosmeticos, lapices, etc... Los animales los estamos usando para llevarlos a un circo, un museo, para hacer trajes de piel, etc... Les repito que nosotros dependemos de ellos y si algun dia se extinguen todas las plantas y los animales pues nosotros tambien nos moriremos.

Why and how humans reproduce?

How humans reproduce?
Humans reproduce having sexual relationships with a male or a female reproductive sistem, the sex cells of a male is called spermatozids and the one of the women is called egg or ova (gametes), when the spermatozoid and the ova joins (fertilization) this produce into a new baby.
Why humans reproduce?
Humans reproduce sometimes by having a new family, others for fun, others for feel it, or sometimes other people for do it and no more but this is happen more frecuency in the teenagers because they dont now how to care a baby, so they abort the baby, or they abandon it. But if you have the age to care a baby it don´t have any problem. Finally this is part of the life cycle.

HUMAN REPRODUCTION


The human reproduction is something nature and it makes part of our life cycle. Humans have sexual reproduction which means that it’s necessary a male and a female sex cell join to reproduce; most of the animals and plants have sexual reproduction too. Those organisms have sex cells that are called gametes. The male sex cells are called sperm (they could be millions of spermatozoids) and the female sex cells are called eggs or ova.

When a female gamete and a male gamete join the sexual reproduction is happening. The fertilization is when fusion of gametes happens. Sexual reproduction makes that the baby or embryo always has genetic characteristics but that not exactly as their parents.

The reproduction is very important in the life cycle and the perpetuation of human being, to make other people have a life too. But life cycle has an order which is important to follow and respect (to be born, to grow, TO REPRODUCE and to die). And it’s important to know that to have a baby is a very big responsibility and you have to be the enough mature to know that a new life it’s a high commitment.

How and why humans reproduce


The humans reproduce because they need to perpetuate their species, the humans reproduce by sexual reproduction.
They need obvusly the men and the wemen because the men have the semen that contain sperm, and the wemen have the ovule that create the baby that it stay there like 9 months and then burn.

REPRODUCING!!!

HOW AND WHY HUMANS REPRODUCE
Human reproduce when the sperm introduce on the ovule and it create a new life is a baby the sperms make a race and the one win enters to the ovule ,the sperm move with the Little tales they have when the sperm enters to the ovule the little tale go out of the sperm ,to reproduce well you have to use protection ,if not the sperm you have will enter to the ovule and you will have many ,many babies or also you will have BIH and you will die because you are not making the good process to reproduce.
Humans reproduce to the perpetuation of species and to make a new life you have to have a very good responsibility ,and also you have to make a very good decision of having a baby because some people that have 13 years think they are so mature to have a baby but some time they abort or also they kill the babies I think you have to make a good decision to have a baby or not and also to have a baby you have to be so mature and have the money to give things to the babies.

WHY AND HOW HUMANS REPRODUCE


Human beings reproduce sexually so which means we need a partner to have sex and make a child. For human beings to create a new life is necessary a man and woman who are not sterile, having sex and that man's sex cell (sperm) which must fertilize the egg. The fetus takes nine months to get out of the mother. For woman can reproduce she should already had her first menstruation
Human beings must play in order to contribute to the perpetuation of the species, because this is very important for us not extinct and we can continue living in our world, which happens to all living beings.

HUMAN REPRODUCTION

For the perpetuation of a kind the specie has to reproduce, and today I am going to talk you about very singular and recognized specie, the human kind
How does human kind reproduce?
The human kind use the sexual reproduction that is when is needed the reproductive cells of a male and the reproductive cells of a female in conclusion are needed both genders.  
The human kind reproduces when the reproductive cells of the male (sperm) and the woman reproductive cell (egg) meet on the fallopian tube, all the sperms that had survive until this point try and try to enter to the ovule for reproduce (but the ovule don’t receive all the sperms because if it receive all you would have like 25 babies ) and the of all the insistence of the sperms many die and like two or one could enter (the tail of the sperm falls) to the ovule this is called fertilization.


We the human kind reproduce sexually because we were created for how we are and also because are needed other many components and factors to reproduce asexually (is the kind of reproduction that is not needed the other gender) like cells that reconstruct their bodies when they separate in two for the parts develop without any trouble.
 Why human kind reproduce?
In most of the cases the human kind doesn’t reproduce for perpetuate the specie, most of the time the people reproduce because they feel inside them that need a baby to take care who and to love, other cases are the failure pregnancies that are the ones that the couple only wanted to have a sexual relationship and at the end they had a surprise they would have a baby or when the woman’s had been violated but yes are cases but a little percent of humans that only reproduce for the perpetuation of the specie.
In conclusion the creation of a new life is full of feelings, errors and things of the destiny.
So live your life step by step and in order.

WHY AND HOW HUMANS REPRODUCE

Why do humans reproduce?

Well is pretty easy to explain why humans reproduce, well is natural and is part of the life cycle to burn, to grow, to reproduce, to die. To reproduce is one of the things most normal in the nature.

Humans reproduce because it is part of our lives, and the nature was created like that and we can't fight with the nature.

Humans reproduce to create new life, not only because of that, people reproduce to have a family, or it can be an accident.

Well but be carefull because if you take the decision to reproduce and create a new life, first think if you have the sufficient resourses to have a baby.

How do humans reproduce?

To reproduce is necessary two people of opposite sex, a man and a woman, the man have a different reproductive sistem and the woman have another reproductive sistem, in the reproductive sistem of the woman have a sez cell called ovule and the sex cell of the man is the spermatozoide, when the sex cell of the men and the sex cell of the woman meet they create a new life.

But if you want to have a baby you most plan the pregnancy.

WHY AND HOW HUMANS REPRODUCE

                                                          REPRODUCTION
HOW DO HUMANS REPRODUCE:
humans reproduse sexuali, it means that female need the sex cell of the male (spermatosoids), and male needs the sex cell of female (ovule) the female and the male depends on each other to create a new life.
they create a new life when spermatosoid the ovule have contact this proces is called fertilization.
WHY HUMANS REPRODUCE:
i think that we reproduce to do that our raze last for a long time and perpetuate , and to complete a life cycle (be born, gorw uo, reproduce and die), it aso is important because is nesesari to give life to others and that they continue doing this cycle for ever so we dosent extinct.
for all there time in life! so do all at the rigth time and enjoy your life!

HUMAN REPRODUCTION




HOW DO HUMANS REPRODUCE?
Organisms have sex cells called gametes, humans reproduce sexually, that means that women and men need each other and their reproductive cells (gametes), in mens the reproductive cells are spermatozoids and in women the ovule, so they join them to create a new life, this is fertilization.

WHY DO HUMANS REPRODUCE?
Humans reproduce for continue with the perpetuation of this specie, and because we come for one cause, for making the life cycle, to born, to grow, to reproduce and to die so we have to reproduce for our specie continues and repites the life cicle so our specie never ends, reproduction is a very important thing because we and everybody depends of it, its natural and normal.

NOTE: When making the decision of having a baby be sure with who and you have to take into your mind who you will support the baby, and also if you alredy have the age or if you are really mature.

In conclusion human reproduction is a very important thing, but responsable sexual reproduction and natural for the perpetuation of species.

Why and how humans reproduce

Human reproduction is a completely natural process by sexual reproduction giving as a result the conception of a child ,always involving sexual intercourse between a man an a woman , During intercourse, the interaction between the male reproductive system and the female reproductive system results in fertilization of the woman's ovule with men’s sperm which after a gestation period is followed by child , and also are some not natural process as the as the insemination methods which do not involves sexual intercourses . The male reproductive system contains two main divisions: the penis, and the testicles sperm are produced. In humans, both of these organs are outside the abdominal cavity. Having the testes outside the abdomen best facilitates temperature regulation of the sperm, which require specific temperatures to survive. The female reproductive system contains two main divisions: the vagina and uterus, which act as the receptacle for the semen, The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the Fallopian tubes. At certain intervals, the ovaries release an ovum, which passes through the fallopian tube into the uterus. Human reproduction is a long process, starting with sexual intercourse, followed by nine months of pregnancy before childbirth. Many years of parental care is required in order to finish with a mature human being.

why do we reproduce ?

we reproduce by the same requirement of any living thing we reproduce for perpetuate our species for continue living but first we have to grow and wait that our reproductive system is totally develop and if not we are going to have complications and the baby can born ill and the mother can die if you reproduce when your reproductive system is to younger because everything is a cycle first you born then you grow you reproduce and you die. And if we doesn’t perpetuate the answer is simple we are going to be extinct.

how we reproduce ?

in the human reproduction we need a pair a male and a female first the testicles of the men keep something called sperms the middle of them produce males and the other middle contain females the head of the sperm contain the adn and all the information about the baby then down of that head there is some kind of energy that is responsible for the tail to move then the spermatozoids participate in some kind of race and there are millions of them first for get out of the testicles the have to go through something called epididymis and there they wait there to go out but that is decided by the male when he want to have sexual relationships and when he have them the sperms are conducted by something called penile urethra next of that they enter into the vagina and there all kind of defenses of the women that try to kill the sperms so everything inside there is against them in the vagina they enter to fallopian tubes and they have to found the ovules there they fertilize and when they enter the tail falls they doesn’t need it any more so it get just the head the one that contain the genetics and information about the baby and next of that the mom have to wait nine months until the baby develop and is ready to go to the world.

why and how humans reproduce


how do humans reproduce ?
humans reproduce sexually , that means that females depend on the male sex cells ( spermatozoids ) and male depends on the female sex cell ( ovule ) to reproduce . WMe depend on each other to reproduce .
Sexual reproduction happens when the spermatozoid and the ovule get together to create a new life . this is called fertilization .
why do humans reproduce ?
well we come to the world to complete a life cycle ( to be born , to grow , to reproduce and then die ) . we are here to reproduce , to help the human race to last for long time. Reproduction is part of the nature , and to keep the world working properly all the species should reproduce. To keep a perfect balance .If we didnt reproduce we wouldent be here . By the religious side , we can see that we come to the world to complete some tasks , and one of them is to get married , and have kids , this is a cycle that shoud be repeated .
in conclusion , reproduction is i think , the most important thing on this world , of this depend that our race or species last for long time and that the world work properly .

! why the human being reproduce ? !


  • a human being can reproduce whit the women reproductive system and the male reproductive system when the male and the women joins something called egg and sperm and when the egg and the sperm joins it is called fertilization and whit that they make a new life a baby .


  • The human being reproduce to create a new life to bring more people to the world and because one of most beautiful things that to a a person can happen is have a a baby



    For me to have a baby is very important because a baby can change my life, a baby is one of most important things in the world because that little person maybe can change al the world


Reproduction is part of the life cycle

We, the humans have a life cycle, is normal, one part of this process is the reproduction; the men has a sex cell (sperm) that is needed to join with the female sex cell to make a baby, in the male reproductive system are the testicles that contain millions and millions of spermatozoids, those can move by their tale, when they are in the female reproductive system, they seek the ovule to go in.

The female reproductive system has an ovary, inside is an egg or ovule that is growing, then it go out in a period of 28 days, if the sperm don't come, the ovule is gonna go out by the vagina.

Is important this part of the life cycle, we need to conserve and perpetuate our specie and give to others the oportunity to live; but, everything has a due course for everything, including the other parts of the process: To be born, to play, to sudy and learn, to live the life in a correctly way, to die etc.

But when you decide to have a baby is because you are responsable and mature to avoid the abandonment, the divorce and other problems.

Why and how humans reproduce


Humans reproduce making sex. The sex is when a boy and a girl put together their bodies and pass an especial “seed” that do a baby.
The ones who pass the seed are the boy and the girl.
We do sex because it is the human cycle. It is normal but you need a lot of caution.
To Care for a baby you need: Money, resources, love, care and affection.
A baby is a seriously thing, because you need to put that baby a lot of attention and a lot of more things.

Why humans reproduce

There are a lot of explications and different cases.
1. Some persons do sex to have fun or to receive money.
2. Other persons do it to feel how it is.
3. Other persons do it to get pregnant.
4. Other persons do it because they love persons but they don’t know if that person is the one.
5. And the last one is because they real love and it is how to do it! With the person you are married and who you know you are going to be all your life.
You can make sex, but with the person you are married with and with the person you know that you are going to stay for the rest of your life.

how and why humans reproduce


HOW

The human being use the system of sexual reproduction as many other living beings in this system there is necesary to have two individuals, of the same specie, but of different sexes each one.

They have to join, so the sex cell of the male called sperm enter to the female reproductive system, to join with the female sex cell called ovule and make a process called fusion or fertilzation.

First than the fertilzation the humans have to grow, so they can be more mature and when their bodies and mind are ready to recive the son that is a new life.



WHY

All the living beings have a life cycle, also every living being have to all the functions in they life cycles .Some of the die very early and the can't do all the functions in their life cycles That functions are to be born, to grow, to be big, to reproduce and then to die. That also happens to the human being. But now many humans are not mature when they have sex and thats why many kids are abortive or are abandoned, because now the teenayers don't think in the responsability that is to create a new life.

WHY AND HOW DOES HUMANS REPRODUCE

WHY AND HOW DOES HUMANS REPRODUCE


WE REPRODUCE BECAUSE THIS IS PART OF THE CYCLE OF A HUMAN. BORN,GROW UP, THEY REPRODUCE AND FINALLY DIE. THIS IS REALLY NORMAL PROCCES AND IF WE DONT REPRODUCE THE WORLD WILL BE ALONE. THE MALE HAS A REPRODUCTIVE SISTEM THAT IS FORM BY THE PENIS AND THE TESTICLES. THE FEMALES REPRODUCTIVE SISTEM IS MADE BY THE VAGINA, CERVIX, UTERUS, E.T.C. THE WOMEN HAS A CYCLE CALLED PERIOD AND THE PERIOD IS CALLED MENSTRUATION. THE FIRST MENSTRUATION OCCURS WHEN YOU ARE 11-12 YEARS OLD. WHEN IT CAMES FOR THE FIRST TIME YOUR BODY IS TELLING YOU THAT YOU ARE READY TO BE A PARENT ,BUT IN THE CORRECTLY TIME. THIS PERIOD IS 28 DAYS LONGER. THE PENIS COME TROUGH THE VAGINA AND IT DEVELOPS A LIQUID CALLED SEMEN. WHEN THE SEMEN IS DEVELOP ON THE VAGINA. THE WOMEN PRODUCE SOMETHIG CALLED OVULES THAT IS MADE DURING THE PERIOD. THE MALE DEVELOPS MILLIONS OF SPERMATOSOIDS AND JUST ONE FECUND THE OVULE. WHEN THE OVULE IS FECUND STARTS A PROCESS OF FORMING THE FETUS OR THE BABY. IT TAKES NINE MONTHS TO FINISH FNISH.

why and how we reproduce?

Because that is the cycle, to create a new life for we never get extinct. Humans or living things have to reproduce for the species live for generations.
The living being have to reproduce with a partner, but the other way to reproduce is asexually that is not necessary to have a partner like the sea horses and some plants that can use that option. The reproduction is something normal in the world but all cannot do it because has some problems. The humans have to introduce the penis in to the vagina then the sperm swims in the semen to get into the ovule and like 20 can get in at the same time and like we create a new life.

HUMAN REPRODUCTION


What is reproduction?

Reproduction is a biological process by which new offspring individual organisms are produce from their parents. Each individual organism exist because the reproduction.


How humans reproduce:

Sexual reproduction happens when a male gamete and a female gamete join. This fusion of gamets is called fertillisation. Sexual reproduction allows some of the genetic imformation from each parent to mix, producing offsprings that resemble their parents, but are no identical to them. In this way sexual reproduction leads to variety in the offsprings. Animals and plantscan reproduce using sexual reproduction. The male sex cells are called sperm and the female sex cells are called eggs or ova and the sex sells are called gameters.


Why humans reproduce:

Humans reproduce for a big cause that is to create a new life, also they reproducce because is a have more and more humans to perpetuate our kind and doesn´t let it extint but we reproduce to satisfy a gigant need that was hat male and female get together and have a safe sex releation from my point of view but we are thinking on aborting especially the teen girls that doesn't protect so when they now they are pregnant they abort and that depress them and they are killing a new life.

Mi problematica es:
Las necesidades humanas destruyen otras especies.
Las preguntas que tengo son:
¿Por que se destruyen las especies?
¿Que quedaría con la especie humana?
¿Que pasa si no existieran otras especies?
Temas:
Los humanos necesitamos mucho para vivir, osea los recursos que nos da la tierra para vivir, los recursos que los humanos necesitamos para vivir
Encontré que:
Los humanos estamos destruyendo todo a su paso.

FRAGMENTATION¡¡¡


FRAGMENTATION

THE FRAGMENTATION IS A METOD OF ASEXUAL REPRODUCTION. THE FATHER DIVIDE HIMSELF IN TWO PARTS AND ALWAYS THE LIVING BEING THAT IS BORN IS ALWAYS IDENTICAL TO HIS FATHER¡. AND THIS CAN MULTIPLICATE REALY ON BACTERIAS.
EXAMPLES




REFLECTION

1) IS NOT A GOOD LOOKING BECAUSE THEY ARE UNNICELLS AND THEY DONT DO WHAT PEOPLE CAN DO, THEY ARE BACTERIAS, PROTOZOOS, FUNGI, E.T.C. BUT THERE I THINK WE HAVE A REALY GOOD ASPECT THINKING ABAUT THE ASPECT OF CLONING BECAUSE OUR SPECIES WILL NOT EXTINCT AND THAT WE COULD DO IT WITH THE ANIMALS THAT ON RISK OF EXTICTION BUT THE CLONATION DOES NOT EXIST YET IN HUMANS HABITAT.

2) THE THING THAT WOULD IS THAT IF WE CLONATE PEOPLE WE ARE not GOING TO DISAPPEAR IN THE ALL WORL AND THE TECHNOLOGY WOULD ADVANCE MORE AND MORE. OUR LASTS NAMES WOULD NOT DISAPPEAR AND I THINK THAT IF WE CLONATE WE COULD DO BIG THING FOR THE WORLD AND FOR US¡¡¡¡¡¡¡¡¡¡¡¡¡

REGENERATION

Regeneration is when you replease parts of your body that can be very ,very damage.Every speices haves a caple of regeneration of bactirea of the humans ,they are many multi-cells that can repeare the damage you had or have on your body.
.If asexual reproduction cloning is natural ,why is negative in humans?
because our cells work in a different way than the plants or animals cells work in other cells.Also because the plants have seeds and when the plant grow is equal to their mom.
.What could happen if humans clone?
I think we would be unhappy because we cant make nothing because there is another person equally to us and we will not work like we work in the past ,I think the tecnology is so avanced that can win in the intelligence to the person or human being.
Juan Sebastian Corzo Millan

REGENERATION =O

On the living things are two kinds of reproduction, the sexual and the asexual but today I am gone tell you about the asexual reproduction.
The asexual reproduction is when an individual doesn’t needs from the other sex for create a new live. Are many examples like the regeneration that is one way to reproduce asexually.
REGENERATION
Is when the organs demonstrate that can regenerate a part of the body that had drops from them, then the part of its body that falls develops and grow like clones of the original organism and the cells from the organism are replaced when it is needed.


QUESTIONS
If asexual reproduction (cloning) is natural in some organism, why is it negative in humans?
-Because in our daily living it is normal for us (humans) to see the creation of a new live by pairs (female and male) no only by a male. And also because would be so strange to see the meddle of a boy developing without a half would be something that has not been created for us the human kind to reproduce would be something abnormal in our specie.
What would happen if humans clone?
- As I already say the human kind had no be created to these kind of reproduction because are needed other many components and to make this work difficult work that why I appreciate to much the nature because it is so perfect that can create another living thing cutting themselves in two, so a congratulations TO THE NATURE ;)  



Asexual reproduction
(Reproduction)


In asexual reproduction, only one parent cell is needed. The structures inside the cell are copied, and then the parent cell divides, making two exact copies.
Before a cell divides, it must make a copy of its DNA witch is organized.
In a sexual reproduction the cells that give the women and the man are totally different, with that cells they do a baby, it is so especial to some parents to have a baby.
Regeneration is the process that uses cell division to grow body parts.
Regeneration is made regulated by asexual cellular process. And maybe some parts of living things cannot be completed so much because they are asexual process.

fragmentation


In this kind of axeual reproduction the leaving being take out some parts of its body, from this part of the body is the genetic code of the living being and the part of the body of the first individual and the second individual grow from there with the same genetic code of the first undividual.

Trhe organism that use this system are like the yuca and the arracacha.


If the axeual reproduction is natural, why is negative for humans ?

The asexual reproduction is negative for humans because the humans are use tow the sexual reproduction and the axeual reproduction some new for us and the people don't like the new things for them.


what will happen if humans cloning?

If humans clone it will be normal , but all of as will be the same , all of as will have the same of the same genetic code.

by:Santiago Gutierrez

The Fragmentation


This type of reproduction can be classified as an asexual mechanism. In this type of reproduction a parent creates a genetically identical to individual (clone) of the parent.

Starfish:
Sometimes a new starfish can come from the cutting arm of an other starfish, but that just occurs when a peace of the arm have a fragment of the mouth of the starfish.

Conclusion:
I think the asexual reproduction is not well seen in humans because if all of us are equal all the thinks would be boring because you can’t tell someone something like, "you are pretty" because all the people is the same; I think is bad too because people can’t express their love to others because you can’t have sexual relationships and have sex is like a form of express your love to the person you love.

                                                          FRAGMENTATION
i shose fragmentation because wen i read i understan it so easy and it was so interestin.
definition of fragmentation: gmentation or Clonal Fragmentation is a form of asexual reproduction or cloning where an organism is split into fragments. The splitting may or may not be intentional. Each of these fragments develop into mature, fully grown individuals that are a clone of the original organism. If the organism is split any further the process is repeated. Fragmentation is caused by mitosis.
"if asexual reproduction(cloning) is natural wy is it negative on humans?"
i think that is  negative because the have only tried with animal so they are like a little of scare to trye snd that the clon  is so deformed or have 4 eye or 2 harts or thing like that.
"what could happen if humans clone?"
 may be it could be a very good experiment but also  a very dangerous because if a molecul move the proces can damash and yhe clon could be a phenomenon.

DEFINITION: Fragmentation or Clonal Fragmentation is a form of asexual reproduction or cloning where an organism divides into fragments. Each of these fragments develops fast and good that are a clone of the original organism.

Fragmentation is seen in many organisms such as molds, some annelid worms, and sea stars.The division of two elements of single-celled organisms such bacteria, protozoa and algae is a type of fragmentation.

Molds, yeast, and mushrooms, all of which are part of the Fungi kingdom, produce tiny filaments called hyphae. These hyphae obtain food and nutrients from the body of other organisms to grow and fertilize. Then a piece of hyphae breaks off and grows into a new individual and the cycle continues. Fragmentation is observed in nonvascular plants like, liverworts and mosses.

REFLECTIONS: If asexual reproduction (clonning) is natural, why is it negative in humans? Because the life cicle would be altered and we would never die, also we would have overpopulation because we clone many people and we would have resource shortages of food, and money.

What could happen if humans clone? We will lose the sexual reproduction, and we couldn`t see diversity of type of people, black people, yellow, etc...

Sebastian Gonzalez

Asexual reproduction (Splitting)

The first form reproduction began about 4 billion years ago, when first RNA molecules and then DNA molecules began to make new copies of themselves by letting amino acids hook on to parent molecule and then splitting them off. All reproduction since then has been the same thing DNA molecules making more of themselves-only the DNA molecules have envolved more and more complicated ways to protect themselves and help the process along.


Questions:

1. If asexual reproduction (clone) is natural why it is negative in humans?
Some days ago I was investigating about the problems about the clones. I found that, the humans clones have more probability to have deformations and deseases, so it can cause rejection between the species.
2. What could happens if humans clone?
If all the humans are clones, can cause the extintion of our species, because the scientists think that the clones are not gonna last so much.

regeneration

Regeneration

These is the proses where the a living thing takes a produce by its own, cells reproduce until he get the right figure and a normal size, example the starfish these incredible animal reproduce by the regeneration of cells he produce he reproduce by losing his arm the arm regenerate and then a starfish came out from that peace of starfish.

Asexual reproduction is a process in which a living being that can reproduce asexually produces both things are needed to help the perpetuation of their species to continue generate life, in the case of humans is a sexual proses and we were designed to reproduce with another living being to perpetuate our species. Cloning is a process which generates a person or objects completely the same but if we clone a human being would be contributing to overpopulation.

by Santiago López

FRAGMENTATION !

The fragmentation is the asexual reproduction when an animal split into fragments and that fragments became in a new life. Sometimes the animal split intentional. Fragmentation is caused by mitosis.

The sea star is a good example, when her legs divide from that leg some others start to grow and it make another star. There are also the Annelid worms, corals, fungi, planarians and lichens.

REFLECTION: I think that the reason because people don’t think good about the asexual (conation) reproduction is because the conation is broking the normal life cycle of a human being which is be born, grow, REPRODUCE, and die. And I think the problem if all were clones is to start seeing that everyone is the same which makes you ignore what you could do like to make a family and to see what is really beautiful.



FRAGMENTATION: the fragmentation is when an asexual animal separate it reproductive cells system in the quantity they need for create a female or a male.


I think that the asexual reproduction in humans is imposible because the humans need to have sexual reproduction with a female and a male and it cannot be because all living things have different ways to reproduct , and also they reproductive system most be different than ours so they can have that capacity to reproduct by them selfes .

I think that if the humans clone that would be bad because every single human have a personality and all of them are especial how they are and in these society every one help the planet to be in balance and if we get clonedthe world would be like a robot world all people would have the same prsonality the same actions and the same way of living and i woulnt like that because you need to interact with other people and know their opinion not just yours

!! Fragmentation !!


  • the fracmentacion is a type of reproduction, where an animal is in 2 or more dibide fragments .


QUESTIONS:
because in animals is more common to clones and that the cloned animals for help them to dont
extinct and not comon in a humans but also can be cloned humans but it is more seen in animals.

QUESTIONS:


is if a human clone, the clone Would Do the Same as the real human example, if I clonedmy clone ami going to do Exactly what I do if I run the neck runs etc and Humans willNever Be Extinguished .

Fragmentation

The fragmentation is when some species reproduse but of an asexual form (cloning) or (divided), they grow paste to them and when they have the size for survive they go out of they.
1. Because the humans can have anormal things when they reproduce like that.
2. We would see each of us many times and the sobre poblation would be much more than now.

fragmentation


fragmentation is a way of reproducing asexually . this way of reproducing is were a new organism grows from a fragment that falls down from the body of his parent , this little fragment grow and it transform into a mature individual . there are some individuals that reproduce by fragmentation like the starfish .

1. if asexual reproduction is natural , why is it negative in humans ?
humans come to the world with one intention , to reproduce and create a family , composed by a man, a woman and their kids , this is what people that belive in God say , i belive this . also because humans were created to reproduce sexually , woman depend on the male sex cells (spermatozoids) , and a men depend on the female sex cells ( ovule ) to reproduce .

2. what could happen if humans clone ?

each human being has its own identity , if you were clonned you could feel that they took your own identity , if you shared your life with somebody else , you could not be a unik person . when you were born you were supposed to have 50% of your dads gens and 50% of your moms gens , that makes you a unik person , nobody can look like you .
if everybody was cloned the diversity could be over , we will look the same , there wont be diferent races .

Fragmentation


Fragmentation:
In this type of reproduction, a new organism grows for a small fragment of the parent body, the animal or plant breaks into small pieces wich develop into a new organism, but in short words this is to make a clone. This is more common in plants and less in animals. For example the worms have asexual fragmentation and their process is that the worm brake up into 9 or 8 pieces and each piece is a little
baby so they start to grow into a mature worm and then it repeat the same cycle. In the plants the fungi have the asexual fragmentation and their process is that the fungi start to die so they brake in little pieces and then it start to grow othertime.
If asexual reproduction (clonning) is natural, why is it negative in humans?
I think because the humans are not prepare to start cloning and also because the bodies will start to change and we dont have the responsability to manage this problems.
What could happen if humans clone? I think it would be more wars, diseases and the consequences will be horrible because it would may cause more global warming and the species will not exist any more and it would be more superpoblation. So i think that if humans clone it would be a bad idea.

REGENERATION

Regeneration is the ability to replace damaged or missing body parts.Some organisms can regrow damaged or lost body parts like the starfish.
Regeneration is the process that uses cell division to grow body parts.regeneration is made  regulated by asexual cellular process.And maybe some parts of living things can not be cpleted so much because they are asexual prosess.
if a asexual reproduction (clonning) is natural,why is it negative in humans? what could if humans clone? :
because the body is not appted to that
because maibe in humans its body maibe dont works like if have to work normaly because is something missing.


REGENARATION

Kinds of individuals that use regeneration :

How it works:
In the regeneration, the piece of a parent is detached, it can grow and develop into a new individual completely.

Reflections:

1.If the asexual reproduction is negative in humans they would never die and always there would be an exact clone of each person, not only one there would be alot of clones and it wouldn't be the same life cycle for humans or worse humans will doesn't have a life cycle, as asexual reproduction is common in plants the sexual reproduction is common in humans.
2.Like i said in the last answer the humans wouldn´t die because they will make more and more clones of them and the life cycle of humans will change or maybe it we would´t have a life cycle.

Fragmentation


Fragmentation is a form asexual reproduction or clonning where an organism is split into fragments. Fragmentation is caused by mitosis.Fragmentation is seen in many organisms such as molds, some annelid worms and sea stars.Binary fission of single-celled organisms such bacteria, protozoa and many algae is a type of fragmentation.

- If asexual reproduction (clonning) is natural in some organisms, why is it negative in humans?

Well asexual reproduction is totally natural in some organisms, but is not natural in humans because, like asexual reproduction is natural for organisms, for humans is natural sexual reproduction.That's why is negative for humans asexual reproduction.


- What could happen if humans clones?

I think if humans clones, all things will change first because they are gonna be clones exactly like me and I will never die because when I die is going to be another me, and the life cycle is going to change because we never disappear.
Mi tema
Como los humanos estamos afectando a otras especies
Yo planeo investigar algunos animales extintos que se hayan extinguido gracias a nosotros, y quiero comprovar mi hipótesis que es: que los humanos estamos acabando con los otros seres vivos.

NUESTRO PLAN DE ACCION

LA CLONACION DE ESPECIES!

  1. Mi problema es los riesgos que puede causar la clonación humana en un futuro.
  2. Nuestras preguntas son:
  • ¿ Cual es la probabilidad de que los clones humanos salgan con enfermedades?
  • ¿ Como la clonación, tanto humana como animal puede afectar la reproducción?
  • ¿ Como la deformación de los clones puede afectar la reproducción sexual?
3. Temas (Conocimientos):
  • Clonación de plantas y animales.
  • Clonación humana.
  • Ventajas y desventajas de la clonación humana.
4. Encontramos que:
La clonación es el proceso científico de el cual se duplican las moléculas de un ser vivo y se crea otro con las mismas características. Es una creación artificial ya que no se crea naturalmente.
La idea de hacer clones fué con el propósito de que la perpetuación de las especies se conservara más. Pero hacer un clon humano puede tener deformaciones y/o enfermedades importantes en un clon.
Uno de los problemas que encontramos fué que si en futuro el número de clones aumenta, entonces van a ver más enfermedades; y si alguna persona tiene relaciones sexuales con un clon, tal vez pude nacer o heredar deformaciones el cual nos llevaría a la extinción.
