flat =About Me= In the future, I would like to attend college. I am unsure of what I want to be when I am a adult. My favorite sports are basketball, softball, and volleyball. In my spare time, I enjoy swimming, listening to music, and hanging out with my friends. My favorite class in school is English, and my least favorite class is math. My favorite vacation spot is Florida, and my favorite season of the year is fall.

=Flowering Dogwood= The scientific name of the Flowering Dogwood is //Cornus florida//. This tree is related to the Kousa Dogwood; whose scientific name is //Cornus kousa//. Flowering Dogwoods are deciduous trees. They have a smooth margin, is simple, and has opposite leaves. It can be recognized by its showy white or pinkish- white flowers. They reach the height of 30' to 40', and they also have ovate shaped leaves. The Flowering Dogwood has been used in the production of inks, scarlet dyes, and as a quinine substitute. The wood from the tree is used in products such as golf club heads, mallets, wooden rake teeth, tool handles, jeweler's boxes and butcher's blocks.

=American Beech= The scientific name of the American Beech is //Fagus grandifolia.// This tree is related to the Mexican Beech; whose scientific name is //Fagus mexicana//. The American Beech is a deciduous tree. They have toothed margin, is simple, and has alternate leaves. An American Beech grows 20-35 meters tall, and has smooth, silver-grey bark. Its leaves are dark green with small teeth 6-10 centimeters long with a short petiole. The wood from these trees are used in flooring, containers, furniture, handles, and woodenware because the wood is very strong. Also, it is the kind of tree that people carve names or dates into.

=Biomolecules in Foods Lab= I tested peas for my food. I used the Benedict’s test to see if there was simple sugars. It turned out absent. I used the Iodine test to see if there was starch. This test turned out absent. I used the Biuret’s test to see if there was protein, and it turned out absent. Lastly, I used the Sudan IV test to see if there was fat and oils. This test turned out absent. I expected that there would be at least one of these things present in the peas, so it was shocking that all the tests turned out negative.

I made this table by writing the number of groups whose tests came out positive for simple sugars, starches, proteins, and fats and oils. Take the apple for example. 9 groups found that the an apple contained simple sugars, 3 groups found that an apple contained starch, no groups found that an apple contained protein, and 6 groups found that an apple contained fat. An avocado has sugars, starch, and proteins. The egg white only had fats and oils. Ground beef contains starch, protein, and fats and oils. Bananas have all four things tested for along with an egg yolk, an avocado, and liver.
 * Food || Simple Sugars || Starches || Proteins || Fats and Oils ||
 * Cannelini Bean(white bean) || None || 7 || 4 || 6 ||
 * Liver || 2 || 5 || 9 || 9 ||
 * Egg White || None || None || None || 9 ||
 * Avocado || 7 || 9 || 10 || 4 ||
 * Potato || None || 4 || None || 3 ||
 * Milk || None || None || 6 || 8 ||
 * Egg Yolk || 4 || 5 || 9 || 10 ||
 * Peas || 1 || 6 || None || 4 ||
 * Banana || 8 || 4 || 4 || 4 ||
 * Apple || 9 || 3 || None || 6 ||
 * Lettuce || None || 1 || None || None ||
 * Ground Beef || None || 1 || 6 || 6 ||

I expected that there would be protein in the egg white. Eggs are a part of the meat group and since meat contains protein, I thought that eggs would contain it too. Also, I expected that ground beef would contain at least a little of simple sugar. But, the test turned out negative. I also found it shocking that an avocado contains protein. I thought that since it was a fruit that it would be mostly made of simple sugars.

I researched the egg white and it said that they have protein. No groups came up with this conclusion. I also researched milk and it said that it contains simple sugars. None of the groups came up with this conclusion.

No people in our groups had the same exact results. This is the case because we each have different DNA so the results should be different. The amount of DNA that I extracted could be affected by day to day activities such as if you chew gum daily, it could cause you to have looser skin cells. Also, you could have been talking a lot before you did the test and could cause the skin cells to be looser.

=DNA Replication Summary = The first step in DNA replication is to break the hydrogen bonds using Helicase. Helicase is an enzyme that breaks apart DNA. The DNA is then turned into 2 strands. Then after this step, the second step occurs. The second step is single stranded binding proteins attach to keep strands from coming together. The strand of DNA on top is called the leading strand. The strand of DNA on the bottom is called the lagging strand. Following the second step, you go to the third step which is primase attaches to give a starting point. Then after that, polymerase binds and begins to replicate DNA. The fragments of DNA on the bottom strand(lagging strand) are called Okazaki fragments. Ligase is the enzyme that pieces Okazaki fragments together. After doing all of these steps, you will end up with exact DNA copies from one strand of DNA.
