Stem Cells Essay

Stem Cells are unspecialized cells, there are 2 types of  Stem cells, Embryonic and Adult, Embryonic cells are pluripotent, they have the ability to turn in any cell in the body. First the sperm meets the egg, that forms a Zygote and then it forms an embryo and those are the Embryonic stem cells. Adult stem cells are already formed in your body, they can only turn in a certain type of cell not ion every single one, they help all your body whem it is damaged.

People think that the Scientists research about the Stem Cells is killing babies because it consists on gathering  Embryonic Stem Cells to continue the research on what they are capable of doing, but to get this cells Scientistst must destroy the embryo to get them. There is another way of using Stem cells for their research that would be combining Induced Pluripotent stem cells with Adult Stem Cells, which makes Adult stem cells behave as Embryonic stem cells, this research would help on getting the Ethical dilemma out of the way.

In my opinion, Scientists should keep on resarching this, because this could change people's lifes, this discovery can cure countless diseases and recreate people's fingers and even arms, for example on 4 weeks if somebody chops a finger a doctor can inject Stem cells so that this cells act as the cells needed in that part of the body and they can regrow back, and not only this, with more research they could also cure Cancer and other complicated diseases that doctors would need help on.

Questions Genetics 1

1: Nature affects your genes throughout your life when you start getting older, your genes change and you change in puberty until you are an adult, but In my opinion you mostly change by Nurture because everything you chose to do throughout life affects you and your body, for example if you only eat junk food it will make your body weaker and you will be more open to a diseases, but if you eat very healthy you will have more chances of surviving a disease.

2: DNA needs to be copied correctly for your body to have the same process of things and for avoiding trouble inside the body. If DNA doesn't copy correctly 3 main things could happen, It might be good for evolution and make great changes throughout history, it may not be a problem at all or It could be a bad thing for every single cell in your body if it keeps on copying badly it could continue harming future generations of the family, in any case people should be aware of what they do in life for avoiding harm.

3: Sexual reproduction.
Advantage: Every offspring will be born different and some would be stronger or weaker than others and there could be more opportunities for change and evolution. Also the offspring would have more protection from the mother.
Dis advantage: The mother of the offspring may suffer from the pregnancy because it may be too hard for her, it takes more time for the offspring to be born and in the life of the offspring takes time for it to form perfectly healthy and correctly.
Asexual reproduction:
Advantage: The offspring reproduces really quickly and more and more offsprings would be born and there would be more of that species.
Dis advantage: The offsprings are exactly the same and if there is a harmful disease it would wipe out every single species that the disease can affect, also there is almost no chances of evolution for that species.
