Evolution is a theory not a law because Scientists define evoultion as a change gene pool that population changes over time. This rate of evolution is all that is required to produce the diversity of the living things as common ancestors. The thoery of evolution says that life originated, and evolution proceeds by random chance. Evolution is a thoery not a law because in science a theory is a well explained explanation for some aspect of the world. Evoulion is a well substained fact because it has been observed and it explains the sequence and arrangement of fossil record. As well as scientific thoery descent with modication species share a common ancestor. Theres a fact of evolution that species there is a variation within one kind of animal.

How DNA changed we invetigate crimes?
DNA has changed the way we investigate crimes in many different ways. It changes the way we investigate because now we have to make sure that the victim that your accusing has any relation to the crime. That's why the investigation process has changed because now the investigators have to send in a sample of the DNA to the science lab so that they can test it to see whose blood or hair is it . Now the DNA helps out and finds the person most reasonable for the crime that was committed. The DNA show the exact person or people that committed the crime and it helps the investigators know how to put into jail. The two main types of DNA testing are Mitochondrial DNA testing and Y Chromosomes testing. Mitochondrial DNA testing can trace maternal ancestry and there are three regions that are tested. The regions are the coding region, HVR1, and HVR2. The Y Chromosomes testing can trace a person's paternal ancestry and the father is the one that passes his Y chromosomes to the son.

My favorite activity that we did for Biology was the fingerprint lab. The fingerprint lab is my favorite activity because we got to see how many different types of fingerprints are there. Also because is interesting to know what type of fingerprints that u have. To know that each finger of both hands has a different fingerprint types. The least favorite activity that we did in Biology is the kim chee lab. The kim chee looked really disgusting and the smell made me get really grossed out. The one thing that i would change is my understanding of the class and how to do certain things in the notebook that I don't understand that would be the only thing to change.

Gregor Mendel And his pea plant experiment
In his experiment the P1 look all alike. They look all alike because the organisms that are used in this experiment are parent generation and are marked as P and every single pea in the first generation is marked as f1. Gregor learned as he studied more he learned that there were too traits of these peas one of thetriats is recessive and one of the traits is dominant. As he contiuned with his this experiment the paarent generatiion was a self pollinated grown up plants. The second generation of the plants were yellow and smooth but some came out green and wrinkly. But as the F1 plants breed each has an eaqul chance of passing on Y or g units to each offspring. And he came to a conclusion of the experiment oneconclusion was that the inheritance of each trait is determined by the units or the factors that pass on to the descendents. Another conclusion that an indidvual inherits one unit of each parent. The last conclusion the Mendel had was that a triat might not show up in an individual but can be passed to the next generation.

In the Movie Gattaca are the parents allowed to pick traits of their babies?
In the movie Gattaca the parents are allowed to pick the traits of there children. The reason for this is that they wanted to create the perfect human so everyone could be the same and live up to being perfect. The world should not be allowed to do this because it would change the world and the way people see it as we know it. Everyone in the world would be the same and who wants to be the same as other, everyone likes to be consider unique and have different potential then others. That's why alot of people have different ideas than one other that's why the world technology is growing because one person created a better and more efficient invention than another. The world should be able to let parents have natural birth and not want to chose the children's future before the children even is born. The parents should love their children regardless of their flaws.

Government isolation
How far should the government go in isolating people with infected diseases and should they army be involved? The government should isolate the people with the infected diseases because if the disease is that bad we don't want it to get that bad where it could wipe out the whole human race. The virus could be really bad but all the people who really want to do is run away and if the run away and they don't know if there are infected they the disease can spread and spread where the disease could be uncureable. This is where the army should be involved so they could keep the infected poeple in on area so that the disease could not get out and will not spread. The government should keep those people isolated and the army needs to be involved to inforce how bad the diease is.
Protections in entering the hot zone
There are a lot of protections when you enter a hot zone. First you have to make sure that you have your protective suit on so that you can not breath the air of the hot zone. You have to make sure that your siut does not have a tear because if you breath the air you automaticially get infected. That is exactly why the scientists put on the suit and the tape the wrists of their siut and they tape the ankle jut to be very secure that they can not get infected. The last thing that the scientists do so they can honestly secure themselves is using the oxygen so they won't die.
