Cell Size Lab

1. Compare and contrast the three cubes after they were sliced in half. The 3x3 cube had the most white left over. The 2x2 cube had the second most white in the middle and the 1x1 cube had the least white. The inside of 1x1 cube it was almost covered with pink because it was the smallest and the solution could seep through the whole cube. As the cube got bigger there wasn’t a lot of pink. That’s is why the 3x3 had the most white.

2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain. The largest 3x3x3 cube of cell was the least efficient in getting the outside material in. It was just as efficient as the others because it took in as much of the substances. It didn’t bring in as much sodium hydroxide because there was untouched areas in this cell than the others.

3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? Surface area to volume ratio explained the cell model the best. The surface area is the size on the outside. The volume is the total size inside and outside of a cell.

4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.) In a way, it was the most efficient because it got the job done the quickest. But you would think the largest cube could be considered the most efficient because it absorbed ½ a centimeter the whole way around, which is a much larger area than all of the small cube.

They might eat the way they do because of there emotions which make them want to eat to make themselves feel better. Fast food places should change the way they eat because it can change the way they eat and there emotions so maybe they should make healthier food.

2. Why do people eat healthy? Some people eat healthy because they know its better for them and it will be better in the long run. They eat healthy because they know what it can do to you and they probably want to be able to do things then be unhealthy and over weight and cant do anything before they get old.

3. Why do people eat unhealthy? Some people eat unhealthy because if they have kids they might have to run to a whole bunch of places where its just easier to stop at a fast food place. Maybe fast food places should take away most of the junk food and make healthier food so when people aren’t able to sit down and have a healthier dinner maybe they can supply more at there restaurant.

4. Why aren’t people changing the ways they eat if they eat unhealthy? If they have to run places it maybe easier to stop on the way, or just to lazy to make the food, or money situations. I think the prices on junk food verses healthy food need to be changed because in the video food Inc. broccoli was more that Pepsi and chips.

Protist Individual Lab Euglena



1. Euglena moves from lakes,streams, and ponds from being carried by a body of a bird. [] 2. Scientists weren't sure if Euglena were animals or plants because they could make their own food and eat other things. [] 3. Euglena is green, and has a red dot shaped as an oval at the rear end of the cell and it is called the contractile vacuole it is a pigment organelle found at the anterior part of the body and is highly sensitive to light.

Protein Synthesis Review Questions mRNA- brings a code into the cytoplasm for ribosomes to read tRNA- transfers amino acids to the ribosome rRNA- translates mRN 5. What enzyme is used to produce a new strand of RNA? Polymerease 6. Which molecule contains the genetic code? Nitrogenous bases (Adenine, Guanine, Cytosine, and Thymine).
 * 1) What are the steps of transcription? Unwinds DNA into single-strands, One of the strands are used as a template, RNA Polymerase attaches complementary nucleotides to the template.
 * 2) What are the steps of translation? mRNA comes into contact with ribosomes, mRNA sequence are read in sets of 3 nucleotides, the ribosomes begin translation at the start codon which is composed of the nucleotides sequence AUG; the start codon is called methionine, represented as MET.
 * 3) List three differences between DNA and RNA. DNA is deoxyribose and RNA is ribose. In DNA, There is Adenine, Thymine, Guanine, and Cytosine. In RNA there is Thymine, Uracil, Guanine, and Cytosine.
 * 4) List the three types of RNA. And state their function (what they do and where they do it)
