Elissa

= = flat =About Me= My name is Elissa. I run Cross Country and Track. I have brown hair and brown eyes, and I also play the guitar. I act with the Theatre Arts Guild, as well as Drama Club. I want to go to college, but I'm not sure what I want to be yet.

=Black Locust= The scientific name of the Black Locust is //Robinia pseudocacia//. It is related with many other trees such as the Honey Locust, Redbud, Kentucky Coffeetree, and Wisteria. It is a deciduous tree with a smooth margin and alternate leaves. It is compound with a pinnate arrangement. It can easily be recognized by 14-20 quarter-sized leaflets on each petiole, white flowers, and deep grooves in the bark. It as an important tree for bee-keeping, and is planted to stop soil erosion. It is not the best for commercial lumber, but can be used for fenceposts.

=Black Walnut= The scientific name of the Black Walnut is //Juglans nigra//. It is closely related to the English Walnut and the Butternut. The deciduous tree is pinnately compound, and has opposite leaves and a serrated margin. It is easily recognized by the walnuts, which resemble large green tennis balls, its large leaves, and the fact that it is one of the first trees to lose its leaves in autumn. The walnuts from the tree are shelled commercially for foods, and the tree is also used to make dye. The wood is very valuable, and is traditionally used in woodworking such as gunstocks, furniture, and coffins.

=Biomolecules in Foods= I tested egg whites for sugar, starch, protein, and fat. I concluded that egg whites contain protein, but they do not contain sugar, starch, or fat. I expected the egg whites to contain at least a small amount of fat, but the Sudan IV test came up negative. Another member of my group tested peas. She found that peas did not contain sugar, starch, protein, or fat. This also surprised me, because I had thought that peas may contain some protein or sugar.

When you separate the foods in to plant-based and meat-based groups, a trend becomes evident in the biomolecules found in them. In plant-based foods, there are more foods that contain sugar and starches than there are foods that contain fats and protein. However, in meat-based foods, there are more foods that contain fats and proteins. With my former knowledge of food, this seems to make sense.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">I was surprised to find out that starch is present in liver. This is because when I think of starch, I think of products such as bread and pasta. I was also not expecting there to be starch in avocados, but I don’t actually know much about the avocado. One thing that I was expecting was to see protein in lettuce and, because I always hear about how healthy “leafy green vegetables” are for you from Mr. Abright.

<span style="font-family: Arial,Helvetica,sans-serif; font-size: 110%;">Based upon my research, I believe that when milk was tested for sugar and starch, it should have contained one or the other, because nutritional facts states that milk does in fact contain some carbohydrates. Also, I think that bananas should have tested positive for protein during the Sudan IV test. Although they contain a relatively small amount of protein compared to other foods, they still contain about 2 grams of protein each.

=Cheek Cell DNA Lab Homework= <span style="font-family: Arial,Helvetica,sans-serif; font-size: 13.3333px;">Everyone in my group had varied extraction results. This is the case because some people may be able to scrape more cheek cells. Also, the way the person performed the experiment may effect how the DNA compacted. The amount of DNA extracted is affected by your day to day activities because if you chew gum a lot, then there may be less cheek cells for you to scrape because you are constantly scraping the sides of your mouth with your gum and teeth when you are chewing gum. = = =<span style="font-family: Arial,Helvetica,sans-serif; font-size: 13.3333px;">DNA Replication <range type="comment" id="135879">Summary = The first step to DNA replication is to split the DNA into 2 separate strands. To do this, you need to break the bond between the strands. An enzyme called helicase does this. Next, proteins, called single-stranded binding proteins, attach to the strands so that they don’t form back together. After that, another enzyme, called primase, attaches to the top, or leading, strand, and starts off the replication. When this happens, an enzyme called polymerase is able to begin replicating the rest of the DNA. On the bottom, or lagging, strand, pieces of DNA, called okazaki fragments, are formed. Another enzyme, called ligase, binds these fragments together to replicate this strand. Both strands have finished replicating.
