=Cell Size Lab=

The cubes all were colored purple/pink. The bigger two had a little bit of substance that you could see around the edges, but the smallest cube was filled the whole way through with the substance.
 * 1**. **Compare and contrast the three cubes after they were sliced in half.**

The 3x3x3 cube was the least efficient at getting the outside subtances into a cell because it was much larger and denser so the substance had a longer way to go through to rather than the smaller cell.
 * 2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain.**

The volume helps explain what I observed because it helps show how big each square is and how much the substance would have to go through.
 * 3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so?**


 * 4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.)**
 * If** the size of the cell is small **then** efficiency of substances entering it is much grater than a larger one.

=Protist= == Spirostomum -The protists spirostomum can grow to the size of 4 millimeters. http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artoct98/spiro.html// //-They will often bend around pieces of algae and other obstacles since they are so flexible.// //http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org.uk/mag/artaug01/spirostom.html -It reproduces by binary fission http://en.wikipedia.org/wiki/Spirostomum = = =You Are What You Eat= You are what you eat to me means pretty much exactly what it says. For example if you it lean and healthy meats like chicken or fish (along with other healthy foods), you too can be lean and healthy. Another example would be, if you eat too many fatty and unhealthy foods you will be overweight and unhealthy. You can be just like the food you eat either healthy or unhealthy. If you if a variety of lean meats, vegetables, and fruits which are healthy you too can be healthy, but if you eat processed and fast foods which are fatty and unhealthy you can end up being fat or overweight and unhealthy just like the food. You build your body off what you put into it, so you are what you eat.

Some questions that I have include: - People always say to eat junk food in moderation but how much is that really? (Like what is a real amount that is good) - What should I really eat before and after practice? - Is organic food that much better than regular food?

=Biomolecules in Food Lab= **Green Banana** 1. 2. The only biomolecule that I found in my food was starch. After doing some research I found out that, that was incorrect. Unripe, or green bananas contain a lot of starch, and as it ripens that starch changes into simple sugars which is why a rip banana has simple sugar and a green one goes not. So bananas do contain starches, but not simple sugars. I though was wrong about it not having fats and proteins. For my tests they did not show for either but after I researched I found out that they do indeed contain both.
 * || **Simple Sugars** || **Starches** || **Proteins** || **Fats & Oils** ||
 * **Green Banana** || Negative || Positive || Negative || Negative ||

3. The foods that I chose to test are the ripe banana and the unripe banana. I compared my research about the unripe banana to the team “The Doofs” research about the ripe banana. The unripe banana tested negative for simple sugars while the ripe banana tested positive for it. This makes sense because it isn’t still later on when the sugars develop in the unripe banana (which would be when it is ripe). The ripe one also tested negative for starches while the unripe tested positive. This again makes sense because it is the starches in the unripe banana that turn into the sugar of a ripe one, this explains why ripe has sugar and not starch while unripe has starch and no sugar. Then there are proteins which when I tested I found that a unripe banana doesn’t have any but with further research they do, and same goes for the ripe banana, they do have proteins as well though it is small amounts. (I found this with my research because the group had said that ripe bananas do not contain protein but they do, in fact a lot of fruits and vegetables contain protein even if it is not a lot). The protein must remain constant through the ripening of the banana. For fats and oils they both end up being positive. With my test it was negative, but again with research it is really positive. So they both contain fats and oils whether its ripe or not. All of these biomolecules provide __energy__ for our body. I found it very interesting how you can have the same fruit, but depending on its stage (ripe-unripe) the biomolecules can be different. So depending on what you want in your body you need to watch the state that the fruit is in. For example if you don’t want a lot of starch opt for the ripe banana.

=Protein Synthesis Questions=

-RNA Polymerase unwinds the strands. -RNA Polymerase attaches to the complementary nucleotides to the template. -Once the template is matched with the complementary RNA strand, the resulting molecule is called messenger RNA. -mRNA molecule breaks off from the template strand and moves out of the nucleus into the cytoplasm, which begins to translate.
 * 1) -RNA Polymerase binds to the start of a gene on the double helix

-Ribosomes consist of two parts -Ribosomes read the mRNA sequence and converts it into an Amino Acid sequence - mRNA sequences are read in sets of three nucleotides. -The ribosomes begins translation at the start codon -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 complementary anticodon binds. - Ribosome continues this until it reaches the stop codon.
 * 1) –mRNA comes into contact with ribosomes


 * 1) Three differences would be that DNA is double stranded and RNA is single stranded. RNA has uracil and DNA has thymine, and have different sugars.
 * 2) tRNA ( transfers amino acid to the ribosome), mRNA (gets code from DNA), and rRNA (translates mRNA)
 * 3) RNA polymerase produces and new strands.
 * 4) DNA is the molecule.

Marfan syndrome -Long arms, legs, and fingers - Tall and thing body type -Flexible joints -Curved spine -Crowded teeth -Stretch marks (Not related to weight loss/gain) -Flat feet 4. Prevalence: 1 in 5,000 worldwide. 5. The cause of Marfan syndrome is a mutation in the FBN1 gene. This gene codes for a protein called fibrillin-1.
 * 1) Single Gene
 * 2) The only other name used for Marfan syndrome would be the abbreviation MFS.
 * 3) Symptoms include:
