Biology: Evolution




In the past there were many great scientist but here I'll talk about a few. Some of the few are Charles Darwin, Jean Lamarck, George Cuvier and Erasmus Darwin.

Each one of these men had theories. They were all different from each other. Lamarck theory was towards changing the environment Darwin’s theory was towards animals.

The different between these two theories is that Lamarck theory focuses on environment changing. Creating the need to change. Development of new features in order to survive and newly acquired traits somehow get passed down to off spring.

As for Darwin his was variations of heritable features which already normally exist. Environment “screens out" and traits which help survival tend to survive and have more off spring who inherit those traits.

Those two people have one thing in common and that is they'll be new species eventually leading into that we go into microevolution. According to the authors microevolution is evolution on a small scale. With that involves population. According to the authors population means a group of organism that interbreeds with each other. There is also micro evolutionary mechanism. They include mutation genetic drift migration and natural selection. Mutation means having green genes. Migration means green flow. Genetic Drift means produced and natural selection means predation.

In the theory i am convinced that species have changed over time. You can look at different types of animals on line of the same species and see how they are different. So yes i am convinced that species have changed over time and i believe that they will continue to change over time as we go in further years.

Experiment With Cats/ Dogs

We recently had a visit with a man who came and talked to us about cat and dog population. He talked about cats and dogs around the world and how much is to much. The only way you'll know when enough is enough is when you see cats and dogs without a home. I do have four dogs. I had 6 dogs but i had to take one back to the pound because she wasn't getting along with the other dogs. I found one next door to my grandmas house. She was tied up around a tree with no food or water. I was the only one able to reach her. It seemed like me and her were one. She Let me get her untied and from there she became my dog. Well she got pregnant but we were unable to watch her cause she would have them when we were at school or my parents were at work. So she lost them. Then she got pregnant again but this time my next door neighbor watched her. She had her puppies there, but she wasn't able to come home. I was told that were ever dogs have there puppies they have to stay there, and from there on she has lived with my neighbor ever since then. I am still able to see her so I guess thats a good thing.

Out in town I don't see very many dogs out and around. If I do they usually have a collar on so someone might of lost there dog or might of got out. Some I don't see with a collar, but when I see them once with out the collar I don't see them again another day.

GATTACA

Questions about GATTACA!

1. The following terms were used in the movie. How do they relate to the words we use: degenerate and invalid?

         De-gene-erate-- The lost of there genes

         In-valid- a person becoming weak

         Borrowed Ladder

2. Why do you think Vincent left his family, tearing his picture out of the family photo, after winning the swimming race against his brother?

 Maybe because he not a loser or anything and so he feels that since he beat his no problem with brother he can beat anything out in the world.

3. Describe the relationship between Vincent and Anton.

From in the movie Anton and Vincent seemed different. They didn’t look really brotherly like. They were separate from each other. They were two totally different people.

4. When Jerome Morrow said to Vincent/Jerome, “They’re not looking for you. When they look at you, they only see me,” what did he mean? Can you find any parallels to this type of situation in real life?

I think what he means is that even though you are not me when they look at you they’ll see me in your eyes.

5. Choose your favorite character from the film. Explain why you choose that person. Would you want to be that person? Why? Why not?

My favorite character would have to be Vincent just because he didn’t give up. He wanted some thing and he stuck him mind to it.

6. At the end of the film, you are told that the Doctor knew about Vincent all along. Why did the Doctor go along with the fraud? What would you have done if you were the Doctor?

The doctor probably knew about his condition and wanted him to keep his job. He probably thought to himself if someone had to go through all that trouble then he must love the job that he does. Yes I would of gone along with it as well.

7. The technology to do what was done in the movie is definitely possible within the next fifty years. Do you think that Vincent’s world could eventually happen in America? Why?

Yes I do think that Vincent world can happen in American. Anything is possible if you set your mind to do it.

8. What do you think is wrong with the society portrayed in "GATTACA"? What is right?

What I think is wrong is not letting Vincent work as what he wanted to become just because of his condition he had. What I think is right is he believing in himself and wanted to work there and he did something about it so that he can.

 

9. What were the screenwriters trying to tell us through the episode of the 12-fingered pianist? Is anything wrong with engineering children to have 12 fingers if, as a result, they will be able to make extraordinarily beautiful music?

That it shouldn’t matter how many fingers a child has it matters how well a child can play with those fingers

10. You and your spouse are having a child and are at the Genetic Clinic pictured in the movie. What characteristics would you want for your child and what would you ask to be excluded? Why would you make those choices?

 I would want my child to be smart very creative and able to play the piano. I would pick these just because these are what people need in there life or they show have in there life. Not so much the piano, but everything else I said.

 

11. Picture yourself as either Vincent, Jerome, or Anton. Would you have acted the same or done things differently if you were in the same world as them?

Probably not I would have just done what they did in the movie from what I saw I did not see the ending of it.

12. How does the society in GATTACA resemble the type of society America was during the height of the eugenics movement?

It represents that people were strict about there workers.

DNA Sequencing

This is a Graph of the DNA Sequencing.

For Abby she had 1 base change. It was GAG -> GTG. She was a 97% Similarity to others. Which = Point Mutation. Protein = GLU-> VAL Disease?

BOB  THE->STOP= Truncation Mutation

Carol ACC  CTG  AGG = Frame Shift Mutation

1) Each of the other three people does not match the normal control. I say this because something happened in the DNA
2) NO All the protein matches the normal control. I say this because of the change in the DNA of the person
3) For each person I would expect a normal state just because of the protein matches. There is only really one that does not match. Sometimes one can make difference and sometimes it don't.

Here are the Flash cards to the key terms

DNA Extraction Lab

We recently did a DNA Extraction Lab where we actually made DNA. At first it was crazy on how we made it. First the materials that we needed was wheat, water and alcohol. So first we put a couple of pinches of wheat into a test tube. Then we added hot water. As we added hot water we had to stir it constantly for 5 mins. After we did that we had to add the alcohol. We had to had 14ml of alcohol into the test tube. Then slowly we had to tilt the test tube and add the alcohol slowly into the test tube so the water and alcohol were on there own layer.
After we had to wait about 15 min. While the tube was sitting we can start seeing the DNA start rising up into the alcohol area. We notice somethings about the DNA. It was white and slimy. As for the bottom it was a mucus look like.
Some of the things that I thought were happening was that the alcohol was absorbing the DNA while the wheat and water was separating the cells so that the DNA would show up in the alcohol level.
I couldn't believe that that was what DNA looked like. It was so small. It really didn't look like what we seen in pictures how it looks like a latter but all twisted up. I still can't believe we have that in us just to see what we are made of. Know we know for sure that DNA is in fact really in us.

This is what all the scientist said what DNA looks like, but looking at it the way we made it when we did the lab looks nothing like this.

Live birth

For the past two days we watch a video about the life's Greatest Miracle. That was an interesting movie about how a baby is being made and how it starts developing. First it starts out the a women's egg and a mans sperm. Once the sperm as inserted into the women's body the sperm finds the egg and it has to find its way into the egg. Then once the sperm has found its way into the egg it starts to form.

This is a long process to develope a baby. It takes nine months for this to happen. After a couple of weeks the baby starts to form its shape. The the process there are three layers of cells that help develope different parts of the baby. One of them are from the brain and spinal cord and skin another one is for the blood and veins and the last one is for the bone and the structure of the body.

Its weird how a baby takes 9 months to form and a dog only takes weeks to maybe a few months. Sometimes it takes a while for a baby o develop. It looks like the mother who is carrying the baby needs a lot of rest and help. Carrying a 7 lb baby in her stomach till its born is a lot of hard work form one person. Plus with the mood swings that the father had to deal with. Also including the food cravings and the morning sickness that come with it. Thats crazy.

This is what it looks like when a baby is inside the womb. The baby flip upside down means that the baby is getting ready to be born.
