flat =About Me=

Hello, my name is Kristen and I am freshman. I jump long and triple jump in Track and Field and I love to hang out with my friends. I am also a major shopoholic and I love to draw and take pictures in my spare time. I also raise and show lambs for my 4-H project.

=Live Oak= The Scientific name for Live Oak is //Quercus virginiana.//

Live Oak trees are deciduous trees.

Live Oaks are related to the Sand Live Oak trees.

The leaves are simple, also known as palmate leaves, have smooth but slightly wavy margins, and alternate.

Three distinguishing characteristics are Live Oaks produce acorns in clusters of 3-5 nuts, they have dark to light grayish color bark that darkens with age, and they are usually draped in Spanish moss.

Live Oaks were once used to build structural pieces for wooden ships but are mostly used now as ornamental trees because of the wood being hard to saw and dry.

=Black Ash= The scientific name for the Black Ash tree is //Fraxinus nigra.//

Black Ashes are related to the Green Ash and the Manchurian Ash trees.

They are deciduous trees.

The Black Ash leaves are pinnate (compound), are opposite of each other on the petiole, and have a toothed margin.

Three distinguishing facts about the Black Ash trees are that the leaflets don't have stalks, their bark is a reddish brown to gray and irregular and corky with tight shallow *fissures and is somewhat scaly or flaky when rubbed, and the leaves are dark green and smooth on the upper surface and paler with rusty colored hairs along the veins underneath.

Black Ashes are used to make baskets, barrels, and woven chair bottoms with flattened strips of the wood and are also used to make cabinets, interior finishing, and fence post because of the interesting grain patterns.

=Biomolecules In Food Results=

Discuss the food you tested and the results from each of the 4 tests. Also discuss one other food that your group tested and those results. The two foods I have results for are the apple and the avocado. In an apple, starch, proteins, and fats are all absent. Simple sugar is the only biomolecule present. In an avocado, simple sugars, starch, and fats were present but proteins weren't.

Identify the biomolecules (simple sugar, starch, fat, protein) found in each of the foods or you can lump the foods into types of foods and discuss the biomolecules found in those categories of foods (look at all the results from the classes) The foods that didn't have simple sugar in them were white beans, egg whites, potatoes, milk, peas, ground beef, egg yolks, and lettuce. The foods that did have simple sugar in them were liver, avocado, bananas, and apples. The foods that didn't have starch in them were egg whites, milk, apples, ground beef, and lettuce. The foods that did have starch in them were white beans, liver, avocado, potatoes, peas, bananas, and egg yolks. The foods that didn't contain fat were white beans, egg whites, potatoes, peas, bananas, apples, and lettuce. Liver, avocado, milk, ground beef, and egg yolks did contain fat. Avocado, potatoes, apples, and lettuce didn't contain protein. White beans, liver, egg whites, milk, peas, bananas, ground beef, and egg yolks did contain protein.

Compare the biomolecules found in the different foods. You can make a chart or graph to show your data OR discuss the data in some way in your paragraph. What biomolecules found in the foods were surprising to you? Why? What biomolecules did you expect to see in some of the foods that you did not find? Why did you think they would be there? Protein being in peas and bananas surprised me because I never really thought of them as being a type of food to contain it. I was surprised to see that potatoes didn't contain any fat because I've always been told that besides them being a good source of fiber, they aren't really good for you.

Research the nutritional information about some of the foods. Based upon your research, which tests should have been positive instead of negative. The test for sugar in egg whites should have been positive instead of negative. The test for sugar in milk also should have been positive instead of negative. In some tests for the sugar, protein, and fat for peas, they were absent but they are present.

=DNA Extraction Lab Homework= Did everyone in your group have about the same extraction results? Why is this the case? How is the amount of DNA that you extracted affected by your day to day activities?

No, not everyone had the same extraction results. This is the case because we had a different amount of cells in our Gatorade, resulting in a different amount of nuclei that contain DNA. We had a different amount of cells because of how much we scraped our cheeks while swishing the Gatorade around in our mouth. The amount of DNA that I extracted was affected by my day to day activities because of the different foods I ate, the amount of cells that were loose, and genetics.

=DNA Replication Summary = To start off the replication of DNA on the Leading strand, an enzyme called Helicase breaks apart the bonds (Hydrogen bonds) that keep the DNA together. Then, a protein (Single stranded binding protein) attaches itself to the broken molecule to keep the strands from coming back together. Next, another enzyme called Primase attaches itself to the end of the broken DNA strands, which gives a starting point for replication. Another enzyme called Polymerase then binds to the strand and replicates the DNA. One DNA strand that is made when it is broken is called the Lagging Strand. This strand uses Okazaki fragments and Ligase to replicate also. The Okazaki fragments are pieces of DNA that are not connected. These are then connected by the Ligase to create a replicated molecule of DNA. These steps need to happen because when a cell divides, the new cell that is being made needs a full set of genes to be able to function.
