About me

I am in Cross Country and Track, and I do like running if you couldn't tell. My favorite class is Math. I like knowing that everything has a right answer. Other things I like to do are read and be with my friends. Something a lot of people don't know about me is I have contacts and glasses.

Tree: Pin Oak

My tree is Pin Oak. It's scientific name is Quercus palustris muench. A tree it's related to is the Scarlet Oak, except it's a little smaller. It's a deciduous. Its margin is pointed lobe, It's simple, and it's alternate. Three distinguishing characteristics of the tree are it's native to Eastern United states and south Ontario, Canada, it's leaf is mostly hairless except orange brown tuft where each lobe vein joins the central vein, and it's height ranges from 50-75 feet. Even though wood is heavy, strong, and hard, it's used for fuel wood, fence posts, and railroad ties.

Tree: Devil's Club

My tree was the Devil's Club tree. It's scientifc name is Oplopanax horridus. It is related to Fatsia Horrida. It's a deciduous type tree. It's margin is serrated tooth. It is a simple tree and it's a palmate type. It's leaves go off in opposite directions. It a large shrub that is native to the cool moist forests of western North America. It has woody stems covered in brittle spines. A Devil's Club tree generally grows 3 ft 3 in to 4 ft 10 in tall. The tree used to be used by the Native Americans to treat a variety of diabetes and tumors. It was and still is used today to create paints.

Biomolecules in food Lab

Liver
  • Simple: absent
  • Starches: Present
  • Proteins: Present
  • Fats: present
Analysis:
  • Discuss the two foods you tested and the results from each of the 4 tests.
    • I tested the Liver. Simple sugars do not exist in the molecules. Proteins, starches and fats are in the liver. Another food we tested were the avocado. The avocado has simple sugars, starches, and fats. The avocado does not contain proteins. The apple contains simple sugars, but no starches, proteins, or fats. The Egg yolk has simple sugars, starches, proteins, and fats all present.
  • Identify the biomolecules found in each of the foods/types of foods (look at all the results from the classes)
    • Fruits that were tested in the labs were the avocados, bananas, and apples. Most fruits tested positive for starches and sugars and some for proteins, but never any tested for fats.
    • Vegetables that were tested in the labs were cannelini beans, peas, lettuce, and potatoes. Most of the cannelini beans that were tested had starches and proteins, but not sugars or fats. The peas mostly contained starches and proteins, but no source of sugars or fats. Most of the lettuce tested contained neither of the molecules. Potatoes mostly contained starches and proteins, but no sugars or proteins.
    • Meats that were tested were the liver and ground beef. Most of the livers that were tested contained starches, proteins, and fats, but were lacking in the sugars. The ground beef that was tested mostly had fats and proteins, but did not contain sugars or starches.
    • Eggs & Milk were also tested. For most of the tests, Milk didn't contain sugars or starches, but did have fats and proteins. Most of the egg yolks that were tested didn't have sugars, but did have starches, fats, and proteins. Most of the egg whites that were tested did not have sugars, starches, or fats, but did contain source of proteins.
  • 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?
    • The biomolecules found in the foods that surprised me were the fats. Fats were in some foods that are usually considered healthy for us, like bananas or avocados.
    • Other biomolecules that surprised me were that apples had proteins in them. Generally, you think of protein as being a molecule in meats. This lab just proves that sources of protein can be found in a multiple of things.
  • Research the nutritional information about some of the foods. Based upon your research, which tests should have been positive instead of negative.
    • Researched information was on Peas, potatoes, and avocados.For peas, it has a very high number of sugar, so it should have tested positive for sugar. For Potatoes, they also have a high percentage of sugar and should have tested positive. For avocados, they have a high percentage of fats, some proteins, and very little sugars. So the tests should have shown the fats and proteins, but maybe not the sugars.
