=**Cell Size Lab**= After being sliced in half, each cube had purple dye through it although some goes through farther than others because they are smaller. The small one was the most efficient because the substance went the whole way through and the largest one was the least efficient because it only went about halfway through. olume ratio because it shows how much the substance went through. If the cells are small then the substance will go through farther.
 * 1) **Compare and contrast the three cubes after they were sliced in half**
 * 1) **Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain.**
 * 1) **Which of your calculations seems to explain what you observed in your cell models? Why do you think so?**
 * 1) **Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.)**

=Paramecium= -Paramecium can move up to 12x their own body length every second. [] -Paramecium is unicellular and can move digest food and reproduce. -They are only about .02 inches long. []

=You are what you eat= The saying “you are what you eat” means to me exactly what it says. If you eat healthy foods and have a healthy diet, you will most likely be a more healthy person. If you have a bad diet and eat fatty foods, you will most likely be very unhealthy and fat. Being healthy is very important because it can give you more energy and you will be motivated to do more activities. Overall, “you are what you eat” means what it says and you should have a healthy diet so you are a healthy person.

Questions: = = =Biomolecules in Foods= **Processed Oatmeal**
 * 1) Does the serving size make much of a difference if you wanted to eat more of what you were having?
 * 2) Does the “Sensa” food sprinkle actually make the food healthier?
 * 3) Is Gatorade better for you than water?
 * 4) Is it actually good to eat protein after exercising?
 * 5) Is diet pop better or worse for you?


 * || **Simple Sugar** || **Starch** || **Proteins** || **Fats and Oils** ||
 * **Oatmeal** || Negative || Positive || Negative || Negative ||

Starch is the second major component in oatmeal at 12 percent. Oatmeal is a complex carbohydrate; there fore it does not consist of any simple sugars.

Simple Sugars: negative Starch: positive Proteins: negative Fats and Oils: positive
 * Steel Cut Oats**

Simple Sugars: negative Starch: positive Protein: negative Fats and Oils: negative
 * Cooked Rice**

Processed oatmeal, steel cut oats, and cooked rice all have starch and all do not have proteins.

=Biomolecule Extra Credit=
 * 1) ** Does the serving size make much of a difference if you wanted to eat more of what you were having? **A serving size is just a reference amount of food as designed by health Canada. You should actually consider portion sizes, which is what is actually on your plate. I think the serving size would be right and you should eat only as much as it says if you want to get the right amount of that food.
 * 2) ** Does the “Sensa” food sprinkle actually make the food healthier? **The “Sensa Diet” is actually not a diet, it does not list foods in which you should or should not eat. Sensa works with your sense of smell to trick your brain and stomach into thinking you are full. I don’t think that Sensa food sprinkle actually works because all you do is sprinkle stuff on your food, even if it does help weight loss, it is not the right way to lose weight.
 * 3) ** Is Gatorade better for you than water? **Water is good to keep your body hydrated before, during, and after a light exercise session. Gatorade is good for high intensity sport or exercise for an extended period of time or in hot temperatures. Gatorade helps to replace glycogen that is lost in physical activity. I agree that Gatorade is better while playing a high intensity sport or doing a high intensity activity because it will help put the right sugars back into your body.
 * 4) ** Is it actually good to eat protein after exercising? **It is important to have protein in your diet after a work out. Proteins will stop your body from breaking down muscle tissue for energy and start the process of rebuilding and repairing your muscles. I agree with this statement, you should not be eating sugary and junk food after a work out.
 * 5) ** Is diet pop better or worse for you? **Diet pop can cause kidney problems, it can mess up your metabolism, it can cause obesity, it can give you a bad hangover if drank with alcohol, it can cause cell damage, rotting teeth, and reproductive issues. Although diet pop is not good for you, I think that most people think that diet pop is better for you just because it has “diet” in it.

 * 1) What are the steps of transcription? It undwinds, then one of the strands are used as a template, and the RNA polymerase attaches complementary nucleotides to the template.
 * 2) What are the steps of translation? mRNA comes into contact with ribosomes, they read the mRNA sequence and covert it into an amino acid sequence, mRNA sequences are read in sets of three nucleotides, the ribosomes begin translation, tRNA molecules transfer the amino acid to the ribosome, tRNA with a complementary anticodon temporarily binds onto the codon, ribosomes read the next codon and another tRNA with a complemtary anticodon binds, a peptide bond joins the amino acids, ribosomes continue on until reaching the stop codon.
 * 3) List three differences between DNA and RNA Different sugars, one is single stranded, one has uracil and the other thymine.
 * 4) List the three types of RNA. And state their function (what they do and where they do it) mRNA it gets the code from DNA, tRNA transfers amino acids from ribosomes, rRNA, translates mRNA.

Huntington Disease is a chromosomal mutation. Other names for Huntington’s Disease are HD and IT15. IT15 stands for interesting transcript 15. Signs and symptoms of the disease are subtle changes in personality, cognition, and physical skills in the early stages. Characteristically symptoms are jerky, random, and uncontrollable movements called chorea. Other symptoms are hallucinations, irritability, moodiness, restlessness, paranoia, and psychosis. This disease is not prevalent within any particular population, all ethnic groups and races, and both male and female can be affected. This is caused by a genetic defect on chromosome 4. The defect causes a part of DNA, CAG repeat, to occur many more times than it is supposed to.
