flat =Cell size lab:= 1. Compare and contrast the three cubes after they were sliced in half. The big cube and medium cube were not fully pink in the center because it could not fully defuse the substance but the small cube was pink all the way threw.

2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain. The big cell was the least efficient and the small cell was the most efficient because the substance got to way to the center but did not get to the center of the big cube.

3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? I think that the diffusion rate is what we observed the most because if we did not observe the diffusion rate we would not know how fast the substance was going in to the “cell”.

4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. If the cell is smaller it will be able to defuse things easier and it will be more efficient, if the cell is larger it will be less efficient because it would be harder to defuse.

=Protist Lab:=

1. Parameciums are unicellular organisms. 2. Paramecium uses their cilia to find their food. 3. Paramecium also use their cilia to move.

= You are what you eat: = You are what you eat means when you eat something your body uses what you ate. Your body does have a big impact on what you eat because if you don’t eat anything healthy then your body would not be getting the vitamins and nutrients that it needs. Your body uses the materials that it takes in for energy and the energy can be used for a variety of different things such as growing. Therefore people say you are what you eat because your body takes in materials from the food that you eat and uses it for a variety of things.

What effect does too much sugar have on your body? Can too much fiber be a bad thing? What effect does a lack of fiber have on your body?

= Biomolecules in Foods results: = 1. Data: The gelatin had no sugar, starch, or fats, but it did have protein. 2. I found that there no starch, no fat, no sugar, but there is protein. 3. Rice compared to gelatin

Rice only has starch and gelatin only has protein. Proteins help in the repair of tissue and help red blood cell development and starches are used for energy.

What effect does too much sugar have on your body? If you eat too much sugar you could get a disorder called diabetes witch stops your body from making insulin.

Can too much fiber be a bad thing? If you have too much fiber in your diet it could make your body not absorb all of the minerals that it could originally.

What effect does a lack of fiber have on your body? If you have a lack of fiber you could get diseases such as diverticulitis, colon cancer, and irritable bowel syndrome.
