Biology
the science of life or living matter in all its forms and phenomena, esp. with reference to origin, growth, reproduction, structure, and behavior.
The Wonderful Platypus
i think that platypus are the most interesting animals found in Australia. not only is one of the few mammals that lay eggs but on of the few mammals that are poisonous. this animal seems like its a mixture of a few animals and that's why i think its so interesting
Immune System Project Reflection
For our first project in biology we learned about a system in the human body. For example one group got the nervous system, the repertory system and out group got the immune system. Each person in the group was responsible for one task, without one person the project wouldn’t turn out good. My role was creative media. My job was to show how the immune system works in a way that made it easier to understand by the audience. I made an animation of a white blood cell chasing down and destroying viruses. I think it turned out very well and I’m proud of it. If I could go back and redo one thing I would research more on the immune system. One thing I didn’t like about this project was that it seemed that it was a very short deadline. Other than that I loved this project. I liked the openness of the project
The immune system is the reason that we don’t get sick from the millions of germs that we come in contact with every day. Barriers are our first line of defense, an example of a barrier is our skin. The skin acts like a wall that keeps out invaders. The skin has special Langerhans cells that warn the rest of the body about incoming germs. The internal defenses are T-cells (white blood cells). All white blood cells are created in the bone marrow and wait for an invader to destroy. The white blood cells are triggered to attack when an antigen enters the body. Antigens are foreign invaders that enter the body. Antibodies however are the “good guys” that find and destroy the antigen. The white blood cells job is to find and destroy any foreign things that enter the body. Once the white blood cell destroys something it learns how to destroy it if it ever enters the body again. A good example is chicken pox. You only get chicken pox once because your white blood cell already knows how to fight it if once it enters the body again.

Building a tape sculpture sound easy but when you think of how you can relate to DNA exoneration it starts to get more difficult. One way my partner and I showed this in our sculpture is making the neck out of a DNA strand. We did this because without a neck the head wouldn’t be able to control the body and in DNA exoneration you need a DNA strand just to make a case.
Our exonree is Donald Eugene Gates. He was wrongly convicted of assault with a weapon, rape with a weapon, and possession of a weapon without a license. He served 28 years in federal prison before being able to be released by proving that he was innocent.
This project helped me learn more about DNA fingerprinting. In class we learned how to make electrophoresis gel that would tell us if two sets of DNA were a match. It was as simple as adding an electrical charge to a sample of DNA in special gel and waiting for the DNA move through.
