flat =Cell Size Lab Individual Part=

1. Once we cut the three cubes in half, one could see that the solution had diffused into cells about the same depth. Each of the cells diffused the solution at a rate of .05 cm per minutes. In the largest cell, there was still a 2 cm square where the solution was not able to reach do to its thickness. In the medium sized cell, 1 cm of the cell was still not diffused. In the smallest cell the solution was able to diffuse throughout the whole cell because of how small the cell was.

2. The largest cell was the least efficient at diffusing the materials throughout the cell coming from the outside of the cell. The small cell was the most efficient at diffusing materials throughout the cell. When we cut the cells in half the largest cell had the greater amount of the white left over, though the smallest cell had no white left over. Each of the cells

3.The rate of diffusion explains what we saw in the cells and tells how fast the solution diffused into the “cell.”

4.If the cell were smaller then solvent would cover the whole cell in less time making it more efficient than a larger cell. = = =Protist Individual Lab=



=You are what you eat= You are what you eat is a common saying. To me nutrition is a very important thing. I am either bulking up or trimming down. Right now I am on a large bulk up diet and I’m trying to put on muscle mass. Along with a high calorie high protein diet I work out at least once a day whether it’s before school or after. When should I have a meal or snack? How many meals and snacks should I have in one day? How can I get enough calories during a school lunch? Should I start packing lunch and bringing my own food?

=Biomolecules in Food Lab=

1. Your data from the food you tested. 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 biuret test should have been positive with the presence of protein in the black beans, though during the test the results said otherwise. According to the nutritional information, in a half-cup of black beans there is 8 grams of protein. There are also carbohydrates in black beans approximately 20 grams per half-cup. Therefore the monocaccharide test should of been positive because monosaccharides are carbohydrates.

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. Milk and orange juice are two common drinks but their biomolecules are different. Both of the drinks have monosaccharide or simple sugars and both don’t have starches. As for lipids and proteins apple juice lacks these two biomolecules. Milk has lots calcium, which allows the growth of strong bones. As for apple juice, it has a lot of vitamin C which helps out the immune system.

=Biomolecule Extra Credit=

When should I have a meal or snack? I should try to eat six meals a day separating them out equally if I wanted to gain weight.

How many meals and snacks should I have in one day? In order to gain weight I should eat six meals or substantial snacks.

How can I get enough calories during a school lunch? I can pack my own lunches instead of getting the school lunches. This would allow me to get as much calories as I need.

Should I start packing lunch and bringing my own food? Yes, instead of relying on the school lunches I should start packing my own lunches.

=DNA Replication Model Project=

media type="custom" key="25077376"

=Electrophoresis Questions= 1.What caused the DNA fragments to migrate through the gel? The electric current is what causes the fragments to move through the gel.

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, because every person has there own personal DNA. DNA is similar to person fingerprint and none are exactly alike.

3. Based on the results of your gel, what evidence do you have to present to the court concerning this murder case? Suspect 2 has the corresponding DNA with the DNA from the crime scene. Therefore suspect 2 is guilty for the crime, which his DNA proved that he committed.

4. Could these DNA samples have been distinguished from one another if only enzyme 1 had been used? Why or why not? No because then we would only have one example of DNA being similar to the DNA at the crime scene. With more enzymes the more matches we would be albe to see in the two samples of DNA.

5. Why did you use two different restriction enzymes for each suspect and the evidence from the crime scene? So that if the first enzyme shows that they are all the same the second enzyme may show that only two of the DNA samples are the same.

=Protein Synthesis Flip-book= media type="custom" key="25200744"

=Protein Synthesis Review= What are the steps of transcription? RNA polymerase binds on to the DNA strand at the promoter region. It then starts to unzip the DNA strand and begins synthesizing a complementary mRNA strand. Once the RNA polymerase reaches the termination sequence, the mRNA strand breaks off and the RNA polymerase stops synthesizing. The mRNA strand then goes through the nuclear pore into the cytoplasm and binds with a ribosome. What are the steps of translation? The ribosome brings in tRNA molecules with anti-codons that bind on to the mRNA strand and leave the amino acid they carry. The once the amino acids are bonded by a peptide bond on to the other amino acids. When it reaches the stop codon, no amino acid is brought in and the amino acid chain in complete. It then folds up into a three-dimensional shape in order to get its unique function. List three differences between DNA and RNA DNA- Deoxyribose sugar, double stranded, Adenine-Thymine

RNA- Ribose sugar, single stranded, Adenine-Uracil List the three types of RNA. And state their function (what they do and where they do it) mRNA- messenger RNA, transports the genetic code from the nucleus to the cytoplasm

tRNA- transfer RNA, transfers amino acid to the ribosome.

rRNA- ribosomal RNA, provide a ribosome and builds protein. What enzyme is used to produce a new strand of RNA? RNA Polymerase Which molecule contains the genetic code? DNA molecule

=Hypercholesterolemia=


 * 1) Hypercholesterolemia is a single gene mutation, it can be the mutation of several genes.
 * 2) Another name for hypercholesterolemia is high blood cholesterol and hyperlipidemia.
 * 3) Symptoms include lack of blood flow to heart resulting in chest pains, lack of blood flow to legs resulting in calf pain, and yellowish patches of cholesterol on the eyelids.
 * 4) Over 34 million American adults have this condition.
 * 5) Hypercholesterolemia is usually caused by certain choices relating to obesity and dieting. It can be genetically caused by the mutation of several genes.

=Intro activity to fuel economy=
 * 1) I noticed that the actual price of the gas is generally less than the tax of the gas.
 * 2) For the US, the most common way of transportation is through cars. For Netherlands the more common way of transportation is trains and railroads. France commonly uses trains. Germany uses buses, trains and bicycles; The UK uses cars, buses, and trains. Spain uses airplanes and train. Canada uses buses and cars.
 * 3) We can concur that the different tax in each country effects on their usage of transpiration. If the overall price is high then there will be more train riders and bicyclists.
