=Cell Size Lab= 1. After the three cubes were sliced in half, you could see how far the diffusion went in the "cell". The diffusion went in to the cell about half a centimeter. 2. The "cell" that was most efficient at getting substances outside the cell was the 1x1x1 cube. The diffusion made its way through the entire "cell". The "cell" that was least efficient at getting substances outside the cell was the 3x3x3 cube. You could see where the diffusion got to. It didn't go through the entire block, just a little less than half way. 3. In my opinion, the surface area to volume ratio would be more accurate on explaining the observations I made with the "cell". The surface area to volume ratio shows how far the substance traveled across the surface of the "cell" and how far the substances traveled on the inside of the "cell" as well. The diffusion only went about half way on the 3x3x3 block and went through the whole way on the 1x1x1 block. 4. If a "cell" is smaller, then the diffusion will be more efficient in the "cell". The smaller the size of the cell, the more diffusion will go through. For example, in the blocks of agar, the diffusion of the 3x3x3 block only went through less than half way, and in the 1x1x1 block diffusion made its way though the entire block. =Protists Lab= __Spirostomum__


 * A genus of free-living ciliate protists
 * Belongs to the class Heterotichea
 * Found in both salt and fresh water
 * All of them are elongated, flexible, and highly contractile.

=You are what you eat= I have heard this saying many times before. To my understanding, it means that unhealthy foods reflect on your health and could cause problems and make you sick or unhealthy. Literally, this means that the condition of your body reflects on the nutritional value of the foods that you are eating.

=Biomolecules and Foods= Green Banana

Testing for simple sugars: Benedict's Test Positive: The green banana changed from a cream/white color to an yellow/orange color after leaving it in warm water for three minutes. After some research, I found out that bananas do contain simple sugars.

Testing for Starches: Iodine Test Positive: The banana changed from its original color to to a blackish purple at the bottom and somewhat purple towards the top. Green bananas contain starches, and as the banana ripens those starches will be converted into glucose as the banana naturally ripens. So, because I tested a green banana, it contained starches.

Testing for Proteins: Biuret Test Negative: The Biuret just kind of mixed in with the banana, causing it to be a light shade of blue. The liquids did not change to a deep violet color, therefore it is negative. I researched to see if bananas had protein, and they do. So, my test was incorrect.

Testing For Fats & Oils: Sudan IV Test Positive: When the substance was put into the tube of green banana, a red ring was formed around the top of the liquid. After a little bit of research, I concluded that a banana does contain fats and oils.

3. Compare foods of your choice (for example, looking at all fruits or foods that contain carbs). Be sure to include foods that you did not test. Discuss the results of the tests (the biomolecules that make up these foods.) Make a statement about the biomolecules in the foods, what happens to these foods in your body (what they are used for), and any other information you found interesting through research. Remember to include a link to your sources of information.

2% Milk Simple sugars: Present Starches: Absent Proteins: Present Fats & Oils: Present

Whey Protein Simple sugars: Present Starches: Absent Proteins: Present Fats & Oils: Present

Monster Energy Drink Simple Sugars: Present Starches: Absent Proteins: Absent Fats & Oils: Absent

The foods I compared are 2% Milk, Whey Protein, and Monster Energy Drink. All three foods contained Simple sugars. Also, all three foods had Starches absent in them.

=Mutations= Patau Syndrome

- Is caused by a chromosomal mutation/abnormality - Another name for Patau Syndrome is Trisomy 13. - Some Symptoms of the syndrome Include - * Hernias


 * Seizures


 * Small eyes


 * Small head


 * Low-set ears


 * Scalp defects


 * Clenched hands


 * Small lower jaw


 * Mental retardation


 * Single palmar crease


 * Undescended testicle


 * Skeletal abnormalities


 * Hole, split, or cleft in the iris

- Patau syndrome affects somewhere between 1 in 10,000 and 1 in 21,700 live births. - Patau's syndrome is the result of [|trisomy] 13, meaning each cell in the body has three copies of chromosome 13 instead of the usual two. A small percentage of cases occur when only some of the body's cells have an extra copy; such cases are called mosaic Patau.
 * Close-set eyes - eyes may actually fuse together
