 * 1) All of the cubes had the pink color in .5 cm. Although the 1cmX1cmX1cm was completely colored because the pink came .5 cm in all directions which filled it.
 * 2) They all seemed to be the same with the efficiency of getting outside substances into themselves because they all had .5 cm of pink.
 * 3) The calculation the helped us was the distance of diffusion because we were looking to see how far the pink color in the cell went and realize it was the same in all of the cells.
 * 4) If the is small or large then they will still have the same efficiency but the smaller cell will look like it’s more efficient due to it’s size but they are the same.

Stentor Three facts: [] One of the largest protozoa that are found in water and it’s single celled. You can see stentor without a microscope. It was named after a Greek Hero in the Trojan War.

=You are what you eat= I think you are what you eat means that in order to be healthy you have to eat healthy foods and if you eat junk food you will be unhealthy. If you are unhealthy due to bad nutrition you will may have different problems later on in life like diabetes. Being healthy and unhealthy in my opinion relates to what you eat and many other things. If you are an athlete, like me you’ll want to eat healthier foods to stay in shape for sports. Even if you were not in sports you would want to maintain a healthy life style so it would be a good idea to cut out as much junk food as possible. So I think “you are what you eat means that if you eat healthy food you’ll be healthy and if you eat junk food you’ll be unhealthy.

Questions:

What is the best type of food to eat? Why are some foods so bad for me? Why are plants better for you than meat?

Gatorade 3. I’m comparing carrots and dark chocolate. In 100 g of carrots there is 41 calories and in 100 g of dark chocolate there is 546 calories. There is 0 g of trans fat in carrots and 0.1 g of trans fat in dark chocolate. There’s no caffeine in carrots and there’s 43mg of caffeine in dark chocolate. Carrots have medicinal purposes and they revitalize blood and that’s why they’re used in medicine. Chocolate was used as medicine in ancient Mayan, Olmec and Aztec cultures.

 * 1) Starch was negative, simple sugar positive, protein negative and fats and oils negative.
 * 2) There should have been sugar, shouldn’t of had starch it shouldn’t of had protein and shouldn’t have fats and oils.

=Enzyme Lab= 1. 2H2O2 > 2H2O + O2 2. The amount of reaction between the temperatures of hydrogen peroxide didn’t change. If there was a change it was to small to tell. 3. Catalase is a protein and all proteins are destroyed by heat. 4. Yes enzymes can be used over and over unless it has a change in pH or it’s destroyed by heat. 5. If enzymes like catalase become useless then we won’t be able to have as fast of reactions because catalase speeds up the reaction.

Egg whites are one of the best foods for you. They are low in fat and high in protein. The egg yolk is where the cholesterol and fat are. Foods that are low in saturated fat and cholesterol are good for you. Food that is good for you is often high in fiber and protein and packaged food is never very good for you.
 * 1) What is the best type of food to eat?

Food with saturated fat, which is a fat with the highest number of hydrogens, can lead to heart attack, stroke or narrowed arteries. There are fats that are good for you like unsaturated fat and then there are fats that are bad for you like saturated fats. The main reason certain foods are bad for you is because they can cause health problems if you eat food that’s bad for you like saturated fat.
 * 1) What are some foods that are bad for me?

[]

First, plants don’t have fat. Livestock also causes global warming due to it’s carbon dioxide emissions and farmers have to clear woods to made pastures for their livestock and we don’t want to clear to many forests. Eating plants, which are low in fat, will help keep you from getting heart disease or type 2 diabetes and it helps people have a low blood pressure. Eating red meat is also associated with increases in cancer and heart disease.
 * 1) Why are plants better for you than meat?

= Protein Synthesis Review Questions =
 * 1) What are the steps of transcription? RNA polymerase binds to the start of a gene on the double helix. 1. Unwinds DNA into single strands. 2. One of the strands is used as a template. 3. DNA Polymerase attaches complementary nucleotides to the template. Once the template is matched with its complementary RNA strand, the resulting molecule is called messenger RNA (mRNA). mRNA molecule breaks off from the template strand and moves out of the nucleus into the cytoplasm, which begins translation.
 * 2) What are the steps of translation? mRNA comes into contact with ribosomes. mRNA sequences are read in sets of three nucleotides. Every three nucleotides codes for one amino acid, call codons. There is more than one codon for each amino acid. The ribosomes begins translation at the start codon, which is composed of the nucleotide sequence “AUG”; the start codon is called “methionine”, represented as Met. tRNA molecules transfer the amino acid to the ribosome. tRNA with a complementary anticodon temporarily binds onto the codon. Ribosome reads the next codon and another tRNA with a complementary anticodon binds. A peptide bond joins the two amino acids, as the ribosome continues down the mRNA strand the first tRNA falls off, leaving its amino acid. Ribosome continues on until reaching the stop codon, where the last tRNA falls off, leaving a chain of amino acids, which will then fold upon itself to give its function.
 * 3) List three differences between DNA and RNA. RNA is single stranded and DNA is double stranded. RNA has uracil and it bonds with Adenine and cytosine is gone. Ribose is the sugar in RNA and deoxyribose is the sugar in DNA.
 * 4) List the three types of RNA. And state their function (what they do and where they do it) mRNA- is the messenger and they are created when the DNA strand is split by RNA polymerase and they take the bases from the nucleus to the cytoplasm. Next is tRNA and transfers and there is also rRNA which is the ribosome.
 * 5) What enzyme is used to produce a new strand of RNA? DNA polymerase
 * 6) Which molecule contains the genetic code? DNA
 * 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.

=Turner Syndrome=
 * 1) Turner Syndrome is a chromosomal mutation
 * 2) Another name for turner syndrome is monosomy X.
 * 3) Some symptoms of turner syndrome are webbed neck, vision problems, high blood pressure, short hands, eyelids that droop, arms that turn slightly out at the elbow, and. the girls with turner syndrome are shorter than usual and it only occurs in females.
 * 4) One of every two thousand five hundred females are effected by turner syndrome.
 * 5) Instead of a female having two X chromosomes she would have one chromosome or two chromosomes and one of them have abnormalities.

=Fuel Economy Activity= 1. If the tax is higher then the price is higher as well. 2. The different forms of transportation are by air (planes), by land (cars, buses), by water (ships). 3. The higher the amount of taxes we put on things then the higher price. The more transpiration in an area then the more fuel that is used.
