=** Cell Size Lab **=

**1.**The squares were colored pink and when you cut them all in half the two bigger ones had just a little bit of pink on the inside but the little one was completely full of the pink but they all went in the same distance its just the smaller one was fuller because it didn’t have as much room for the substance to go.


 * 2. ** The 3x3x3 cube was the least efficient at getting the outside substance into the cell because it was much larger so the pink substance had a longer way to go through to rather than the smaller square which the substance only had a little way to go through.

4.If the size of a cell is small then the efficiency of a substance entering a small object is greater because it is easier for the substance to pass through it.

=**Protist Lab**=
 * Spirostomum:**

 * 1. Spirostomum is a one celled protazoan with a central digestive tube.**
 * 2. The beating cilia sweep small organisms into the Spirosomum's mouth for it to eat.**
 * 3. The organism can divide in half and so can the nucleus for reproduction.**
 * 4. The Spirostomum's body has rows of cilia and they beat back and forth to move the organism.**

=**You are What you eat:**=

The saying “you are what you eat” means the type of food you eat determines the kind of life you will have. Such as if you eat a lot of fatty foods then you will probably end up being obese and you wont have a very long life because you may end up have heart problems. Another example is if you eat sugary foods all your life you have a higher chance of getting diabetes and that also determines your life style because you have to watch everything you eat and you wont have as much energy.

 * Some Questions I have: **
 * Is it true that fast foods hamburgers have very little meat content?
 * Why does soaking beans make them more digestible?
 * Why do pasta recipes recommend adding salt to the boiling water?


 * 1) Your data from the food you tested.


 * || Simple Sugar || Starch || Proteins || Fats & Oils ||
 * Whey Protein || Negative || Negative || Positive || Negative ||
 * 2% Milk || Negative || Negative || Positive || Positive ||
 * Peas || Negative || Negative || Positive || Negative ||

2. After testing 2% milk there are no simple sugars, or starched but 2% milk is very high in proteins and fats and oils, I think that after testing this I think that the sugars, fats and oils and proteins should of been positive and the starches should have been negative.

3. The foods I tested were very high on proteins but not so high on sugars, starches, or fats and oils. The food I just researched was an apple raw with skins, which is very high in sugars but has no protein, starches, or fats and oils. Apples can cleanse toxins and stored up fats from your body because apples contain a big amount of pectin and very little fats and oils, and starches.

=Flipbook:= media type="custom" key="25203254"

=Review Questions:=
 * 1) ** What are the steps of transcription? **** The steps, of transcription is **** DNA is transcribed by an enzyme called RNA polymerase. Specific nucleotide sequences tell RNA polymerase where to begin and where to end. RNA polymerase attaches to the DNA at a specific area called the promoter region. **


 * 1) ** What are the steps of translation? mRNA comes into contact with ribosome, Ribosomes read the mRNA sequence and converts it into an Amino Acid sequence, mRNA sequences are read in sets of three nucleotides **


 * 1) ** List three differences between DNA and RNA The three differences are RNA is single stranded is has uracil instead of thymine and instead of deoxyribose is just has ribose. **


 * 1) ** List the three types of RNA. And state their function (what they do and where they do it) mRNA (messenger), tRNA (Transfer), and rRNA (Ribosome) **


 * 1) ** What enzyme is used to produce a new strand of RNA? RNA Polymerase **


 * 1) ** Which molecule contains the genetic code? The DNA molecule **


 * Marfan Syndrome:**


 * Singled Gene**
 * Other Names:** MFS
 * Symptoms:** Vision problems in one or both eyes, defects in the largest blood vessel that delivers blood from the heart to the rest of the body.
 * Prevalence:** Testing is specialized laboratory test that looks for the changes in a person's genetic material.
 * Cause:** Marfan Syndrome is caused by a defect in the gene that encodes the structure of fibrillin and the elastic fibers, a major component of connective tissue.
