flat =Questions for cell size lab=
 * 1) The cells are different and similar. The solution went into all of the cells a ½ centimeter but since they are different sizes they all look different. The smallest one was all colored because ½ cm. in the cell would be all of it around. The biggest cell had ½ cm. around it but it looked less because it was so much bigger than the small cell.
 * 2) The smaller cell was the most efficient and the biggest cell was the least efficient. The smaller cell was more efficient because it let the solution the whole way into the cell unlike the biggest cell that didn’t get close to the center of the cell.
 * 3) The distance of diffusion and the rate of diffusion were the same in all of them but the surface area and the volume are different so the amount of the solution that went in was the same but since the size of the cells were different they weren’t all efficient.
 * 4) If a cell is bigger than it is going to be less efficient.

Euglena can make their own food like a plant but they can also eat other things like an animal. http://www.fcps.edu/islandcreekes/ecology/euglena.htm

Euglenas look to be green but most of the organelles are purple. The nucleolus is pink and the cytoplasm is yellow. http://lifestyle.iloveindia.com/lounge/euglena-facts-9356.html

Euglenas are both autotrophic and heterotrophic at the same time. http://www.ask.com/question/interesting-facts-about-euglena =You are what you eat= When I hear the saying you are what you eat I think of people turning out to be the same as what they eat. The food that people eat affects them in more ways than they think. For example, when a person only eats junk food they will feel very tired and stressed because it is not good for them. When people eat good foods they feel energized because the foods are good for them. Many people don’t care about what they eat and then wonder why they always feel run down. Does the amount of food matter, too? Can you really eat as much as you want when your active?

=Biomolecules in Foods lab= Apple juice is said to have simple sugars and the test proved that statement. Apple juice is said to have starches but the test did not show any signs of the presence of them. Apple juice does not have any protein and the test showed the same result. Apple juice does not have any fats or oils in it.

I chose to look at peas and an onion along with the apple juice I had tested. The onion was negative for simple sugars, negative for starches, positive for proteins, and negative for fats and oils. Peas are negative for simple sugar, negative for starch, positive for proteins,and negative for fats and oils. The different biomolecules do the same thing to our bodies no matter what food they are in. Simple sugars and starches provide energy for our bodies because they are a part of carbohydrates. Proteins help our bodies grow and repair. Fats and oils are used for storing energy. http://leavingbio.net/nutrition%20and%20food_files/nutrition%20and%20food.htm

=Protein Synthesis Project= media type="custom" key="25200722"

= Protein Synthesis Review Questions =


 * 1) ==== What are the steps of transcription? RNA polymerase breaks apart DNA. It uses one strand to make the mRNA. U goes with A and G goes with C. The RNA polymerase breaks off the DNA and the DNA goes back together. The mRNA goes out the nucleus and into the cytoplasm. ====
 * 2) ==== What are the steps of translation? mRNA comes in contact with a ribosome. The ribosome reads the mRNA. The ribosome begins at the start codon and tRNA transfers amino acids. The tRNA has an anticodon and it goes onto the mRNA strand and waits until another tRNA comes so it can have its amino acid have a peptide bond with the other amino acid. The ribosome continues until it reaches the stop codon. The chain of amino acids folds on them and are in a tertiary structure to have a function. ====
 * 3) ==== List three differences between DNA and RNA. RNA is single stranded and DNA is double stranded. ====
 * 4) ==== List the three types of RNA. And state their function (what they do and where they do it) mRNA is a messenger in the nucleus, tRNA is a t in the cytoplasm; rRNA is ribosomal in the cytoplasm. ====
 * 5) ==== What enzyme is used to produce a new strand of RNA? RNA polymerase ====
 * 6) ==== Which molecule contains the genetic code? Nucleus ====
 * 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. ====

Polycystic Kidney Disease 1. It is a single gene mutation. 2. Sometimes it is called ARPKD. 3. Some symptoms of PKD are pain and swelling. 4. Autosomal dominant polycystic kidney disease affects 1 in 500-1,000 people and autosomal recessive type occurs in 1 in 20,000-40,000 people. 5. Mutations in the PKD1, PKD2, and PKHD1 genes cause polycystic kidney disease.

=Intro activity to fuel economy=
 * 1) What relationships do you notice between the fuel economy and the taxes in a given country? The higher the fuel economy the higher the taxes.
 * 2) Do a quick research of the most often used transportation (types of vehicles) for the countries. Driving is used most in the U.S. The Netherlands use cycling to transport. France uses trains to transport. Germany uses buses to transport. Road is used in the UK. Spain uses taxies. Canada use walking or cycling.
 * 3) What conclusions can we draw? The price of gasoline is going up in places that use a lot of it.
