Thought Question

How can mutations affect us as humans?
Mutations can often affect us if they are negative muttations such as a disease, malformation or something that every single person dosent have. 
Example: Being  alergic to all meats can be a muttation if it can easily be passed on from generation to generation affecting you health.

Stem Cell Research

Stem cells are unspecialized cells, that means they dont have a job in particular, this cells are not ordinary cells, this cells can be used to cure many diseases like Alzheimer, Parkinson or heart disease, the way it cures this type of sickness is by creating new cells that will substitute the harmed cells that have the disease.

 People who are against stem cell research mainly look at the fact that is it taking the opportunity of another life that is being stopped from comming and becoming a new human, this can be counted as killing a baby to people who believe that life starts as soon as the sperm reaches the egg. This for christian is stopping nature from happening as well interfiering with life. "The far future can lead to knowledge on how to clone humans, it is hard to say weather this is true, but we have seen devasting consequences of other research programs, even with good intentions such as nuclear research" Nobel prize winne in Medicine or Physiology Mario R. Capecchi 2007.

There are people who believe that stem cells have a positive effect on sciene and medicine, and they are better than any other cell in the human body since it help cure people all around the world from deathful diseases. This could cure diseases easily just with the egg a woman dosent want and a sperm, that lately its been said that stem cells can also be found in a adult body. "Stem cells can divide themselves creating a bigger quantity of cells unlike other cells" says Dr. Nathan Wei. This cells are said to cure the diseases or sickness quicker and easier than any other medication. People are favour to this research since there are made to think the only think is causes is the cure to many diseases.

I think Stem Cells are not on the best interest of people since they are taking away what could be used or what is a baby and putting it on science, many countries do not permit stem cell research due to the materias needed to create the cells. "Side effects of stem cell transplant can be very serious or even life-threatening" Says the  Canadian Cancer Society, This cells may cure many people but they also but peoples life in risk. In my opinion, this treatment should not be a option for anyone suffering from any sickness and stem cells should not be a way of medication.

Summative Questions

1. Which influences who are more - your genes (nature), or your environment (nurture)?
 Give a reason for your answer.

 Who you are is made up by you genes and the environment you live in, the genes take up how you look and sometimes small traits in your personality, your environment can define the way you react to some things, how you feel as well as many other things. Ex: My genes make me brown haired with brown eyes (nature), while my environment makes me happy and cheerful (nurture). I think what defines me the most is my environment (nurture) because it made y personality the way it is while my genes only made a small part of me, the way I look. You could be influenced by you genes if you have a diseases that is geneticly passed, Alzheimer is a genetic disease that can take away your memory slowly by the death of many brain cells, this causes the brain to shrink, making the brain loose nerve cells and connections. Diseases, as well as many other things that are passed on genetictly make up who you are.

 2. What could happen if DNA does not copy itself properly?

 If the DNA is not copied properly and other cells are not able to kill it, it will start reproducing causing a mutation. There both positive and negative mutations. Ex: A positive mutation can be humans nit getting sick, or being born and not being allergic to anything. A negative mutation can be anything that can easily spread, such as humans having a third eye.

3. Give a advantage and one disadvantage of asexual reproduction and sexual reproduction. Explain your answers.

A advantage of asexual reproduction is that it is a way faster process than sexual reproduction. A advantage of sexual reproduction is that the offspring is being protected from the outside until it is capable to protect itself. A disadvantage of asexual reproduction is that every single offspring has the same genes, is exactly the same. A disadvantage of sexual reproduction is that it is a slow process.
