flat =Cell Size Lab= 1. All three cells diffused the solution 5 cm. in 10 minutes. In the smallest cell the solvent was completely diffused into the middle. In the middle sized cell there was a 1x1x1 cm. cube left over after the 10 minutes. In the largest sized cell there was a 2x2x2 sized cell left over after the ten minutes.

2. The smallest cell seemed to diffuse the fastest because it completely diffused the solvent through the cell. The largest seemed to be the least efficient because it diffused the least based on size.

3.The rate of diffusion, or .05 cm. per minute, seems to explain what we saw because it tells how fast the solvent diffused into the agar.

4. If the cell is larger, then it will take longer for the cell to diffuse a solvent.

=You Are What You Eat= You are what you eat means that what you eat effects you by giving you more energy or helps with your organs. If you eat a lot of fat you will become fatter. If you don’t get enough carbohydrates your body won’t be as efficient as if you do get enough. If you eat certain foods they will help your organs, like carrots help your eyesight. If you don’t get enough vitamins and minerals you could become sick for instance if you don’t get enough iron you can get iron deficiency anemia. If you eat enough of the good food you will start to lose weight gradually. In conclusion, this is what you are you eat means to me.

Questions
 * 1) What all can give you energy?
 * 2) Is fiber healthy for the human body?
 * 3) What is your body’s preferred source of energy

=Biomolecules In Foods Lab= The onion changed from a light green to an orange so it is a monsaccharide or a disaccharide. The onion doesn't have any starches in it because it started out as orange and stayed orange for the duration of the time. The onions have proteins because it started out at a lighter green and then changed into a darker green. The onion doesn't have any fats because it didn't become a deep red color.

The Biuret Test should have been positive for proteins. The Benedict Test should have been positive because there are simple sugars in onions. The Iodine test should have been negative because onions do not have starches. The Sudan IV Test should have been negative because there isn't any fat in onions.

The egg and onion both have protein and neither have fat. The onion has simple sugars, but it does not have starch or fat. The onion has starch, but it does not have simple sugars or fat. Food companies are aloud to be up to 20 percent off on food labels.

=Biomolecules Extra Credit=

1. What does your body use for energy? The Body's preferred source of energy is carbohydrates, but it can also use proteins and fats.

2. How many calories does your body need to function properly? To figure out how many calories you need multiply your weight by ten.

=DNA Replication Model Project= media type="custom" key="25077476"

=Protein Synthesis Review= 1. What are the steps of transcription? The Double Helix of DNA unwinds as the hydrogen bonds between the bases of the two 'poly nucleotide' strands are broken down. Enzymes are used. One strand is used as a template to copy DNA "sense strand." Free mononucleotides lying free in the nucleus line up along the sense strand by specific base pairing. Condensation reaction links up the mononucleotides into a poly nucleotide strand. The new strand formed is a messenger RNA. It then moves out of the nucleus through the nuclear poles heading for the ribosomes ready for translation. The DNA strands regain there hydrogen bonds and coil into a double helix again unaltered. 2. What are the steps of translation? Initiation, Elongation, and Termination 3. List three differences between DNA and RNA Thymine replaced with Uracil, Ribose sugar instead of deoxyribose, RNA is single stranded unlike DNA. 4. List the three types of RNA. And state their function (what they do and where they do it) mRNA- Carries the protein blueprint to the ribosome tRNA- transfers the amino acids to growing polypeptide chains rRNA- translates the gene 5. What enzyme is used to produce a new strand of RNA? RNA Polymerase. 6. Which molecule contains the genetic code? DNA

=Huntington Disease=

1.Huntington Disease is a single gene mutation.

2.There are no other names for Huntington Disease.

3.Huntington Disease may cause extreme irritability, depression, or mood swings. It may also affect memory and judgment.

4.Huntington Disease usually affects an estimated 3 to 7 per 100,000 people of European ancestry. In the US about 1 in every 10,000 people get Huntington Disease.

5.The degeneration of nerve cells, neurons, in certain parts of the brain causes Huntington Disease.

=Fuel Economy= 1. The higher the fuel economy, the higher the taxes. 2. US- Driving cars Netherlands- Bicycle France- Train Germany-Buses, Trains, and Bicycles UK-Cars, Buses, and Trains Spain- Airplanes and Trains Canada- Buses and Cars 3. We can conclude that the more the citizens of countries use mass transportation the more the price and tax of fuel.
