flat =Cell Size lab= 1. Compare and contrast the three cubes after they were sliced in half. The cubes were all different sizes but you can only see how far the diffusion went in two of them which were 3 cm cube and the 2 cm cube. 2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain. All the cells were the same so I am sure that all the cells were the same at getting outside substance in the cell. I would think this because the diffusion happened in through the cell all at the same rate so the all were equal. 3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? The calculation that seemed to explain what I observed in our cell models was the rate of diffusion. I think so because all I saw was that the smallest cell didn't have the same rate of diffusion and then I figured out that it was all the same rate of diffusion. 4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.) If the cells are different sizes, then the rate of the diffusion will still be the same rate. =Organelle research= Cytoplasm =Protist Lab= Stentor 1. Stentor are one of the largest protozoa found in fresh water, because of this stentor are observed in class rooms. 2. In the fall is a great time to study these protozoa because the leaves fall into lakes which create bacteria and then all the stentor gather around that decaying leaf. 3. It is named after a Greek hero in the Trojan war because the Greek hero was loud and it is trumpet shaped. All you can hear in a band is the trumpets. http://www.encyclopedia.com/topic/Stentor.aspx =You are what you eat= You have heard the saying: you are what you eat. What does this mean to you? Explain in a paragraph. Then, write questions that you have always wanted to ask about the foods you eat, things you hear on TV, in the news, from your parents, at practice, etc. Here are a few basic principles that are understood by scientists and doctors and have been proven in studies that can start your thinking and questioning: This means if you eat healthy you will be healthy and be active. If you eat terrible you will probably are going to be a couch potato and a sit there watching tv and eat junk food and be a fat slob. You will order pizza wings like crazy and sit there and lick your over sized fingers to get every little bit of the sauce off.
 * 1) What type of cell is it found in? It is found in both Eukaryote and Prokaryote cells.
 * 2) What is its structure (composition)? How does the structure help the organelle to do its function? It is composed of water, dissolved ions, small molecules, and large water-soluble molecules (such as protein). The structure helps because those things form a jelly-like substance so the organelles can stay in one general area.
 * 3) What is its function? Why is that important? The function of cytoplasm is to hold the organelles in one general area and to separate the organelles from the cell membrane. It is important because then organelles won't bump into each other or the cell membrane.
 * 4) How does the organelle achieve that function? What are the mechanics or the processes that it goes through?
 * 5) How is the function regulated? The function is regulated by the
 * 6) What is the connection between the organelle's function and the cell's function?
 * 7) What would happen if the cell did not have this organelle? Then the organelles would bump into each other and the cell membrane.

How much cholesterol is in an egg yolk? Will T.V. affect your appetite? =Biomolecules food lab= > > media type="custom" key="25077518" > > 2. Would you expect your personal DNA fingerprint to be identical to any of the persons tested in this lab? Explain how you would confirm or refute this. No, I wouldn’t expect my personal DNA fingerprint to be identical to any of the persons tested in the lab. Every persons DNA is special to there own specific cells. > > 3. Based on the results of your gel, what evidence do you have to present to the court concerning this murder case? The second suspect has the same length of DNA found at the crime so he is guilty. > > 4. Could these DNA samples have been distinguished from one another if only enzyme 1 had been used? Why or why not? I don’t think the DNA samples could have been distinguished from one another if we only had enzyme 1 because if we had more enzymes we can make more matches. > > 5. Why did you use two different restriction enzymes for each suspect and the evidence from the crime scene? We used two different restriction enzymes because then you can find more matches.
 * 1) I had whey protein. **Mono/disaccharides**: positive **Starch**: negative **Protein**: positive **Fat**: positive
 * 2) Research the biomolecules (nutritional information) that are found in the food that you tested. Which tests should have been positive (present) or negative (absent) based upon your research? **The tests that should have been positive are the mono/disaccharides and proteins.**
 * 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. **Strawberries, mango, and mangosteens are the three foods that i will be choosing. First off they are all fruit the results of the test would be positive for mono/dissacharides because fructose is found in fruit and it is a form of carbohydrate. They are also made up of starches, so that would be positive because that is what the excess glucose that the fruit doesn't use is stored as. These fruits are mainly used for energy because they are all carbohydrates according to** http://healthyeating.sfgate.com/fructose-absorption-digestion-4553.html **the small intestine can't break down whole polysaccharides so your body has to classify if fructose is in the form of sucrose, sucrase, or an enzyme. Then it must break down whatever it is into single fructose or glucose molecules then it enters the lining of the small intestine.**
 * 1) 1. What caused the DNA fragments to migrate through the gel? The electric current is what caused the DNA fragments to migrate through the gel.

media type="custom" key="25200572" =Protein Synthesis Review Questions= = Mutation Questions =
 * 1) What are the steps of transcription? RNA polymerase comes unzips the DNA and copies the complementary strand. The mRNA strand then exits out of the nuclear pore.
 * 2) What are the steps of translation? The strand goes with a ribosome and it goes down the line of codons and the tRNA with the anticodon comes in and binds with the complementary codon and the tRNA also has an amino acid on top. The anticodon falls off of the tRNA and the amino acid forms peptide bonds with the other amino acids. The amino acids curl together to form the tertiary structure of protein.
 * 3) List three differences between DNA and RNA. RNA has three forms / RNA has uracil in for thymine/ and the sugars are different ribose and deoxyribose.
 * 4) List the three types of RNA. And state their function (what they do and where they do it) mRNA is a messenger RNA carries genetic information used to make proteins / tRNA which is transfer RNA which transfers anticodons and amino acids/ rRNA which is ribosomal RNA associates with a set of proteins to form ribosomes
 * 5) What enzyme is used to produce a new strand of RNA? RNA polymerase
 * 6) Which molecule contains the genetic code? DNA
 * 7) Be sure you can transcribe a gene and determine the complementary amino acids.
 * 8) Be sure you can identify all the parts (see flip book requirement list) of both transcription and translation.
 * 1) XYY Karyotype is a chromosomal mutation.
 * 2) The other name of XYY karyotype is XYY syndrome.
 * 3) The symptoms of this syndrome is severe acne and boys grow taller.
 * 4) The prevalence is 1 in 1,000.
 * 5) The cause of this syndrome is having an extra chromosome.

=Intro activity to fuel economy:= 1. The lower the tax the lower fuel economy. 2. The car is the most commonly used vehicle. 3. In conclusion a lower tax will get you a lower fuel economy and it depends on the vehicle that you use that effects the fuel economy and taxes.
