====2. The small “cell” seemed to be most efficient at getting outside substances into the cell. The largest “cell” seemed to be least efficient at getting outside substances into the cell. This is because in the 10 minute time period that the cell was in the substance, it did let some of the substance in but since it is much bigger than the smallest one, it had more space to fill in that short time.====

====3. The calculation we used when observing our cell model was rate of diffusion. We found the rate of diffusion after we let the cubes in the substance for 10 minutes. After we took the cubes out of the substance, we measured how far the purple went into the cube. This was 0.5cm on all sides. This means that it would have taken another 10 minutes to fill the 2cmx2cm cube, and an extra 20 minutes to fill the 3cmx3cm cube.====

=Protists=

Spirostomum
Facts about the Spirostomum: They can grow to 4mm long. They can be found in both salt and fresh water. They can contract their bodies faster than any other living cell in the world.

=You Are What You Eat=

The saying “ you are what you eat “ is basically saying that if you eat unhealthy foods, over time, your body will become unhealthy. If you eat healthier foods, your body will be healthy. For example, if you heat healthy meats and proteins, you will have stronger, leaner and healthier muscle.

Questions:
 * ====Is it true you should drink 8 glasses of water a day?====
 * Are organic foods the safest and the healthiest?
 * Do energy drinks actually give you energy?
 * Are frozen foods less healthier?
 * Will to much sugar give you diabetes?

__ Beef __

Fat-- Positive
2. After researching beef, I found that beef has 136g fat per pound. This proves that fat is tested positive. I also found that beef has 65g of proteins per pound. This proves that beef should be tested positive in proteins, which I did. I found that beef does not contain simple sugars or starches which is what I found in the tests I have done.

DNA Replication Model

What are the steps of transcription? RNA Polymerase binds to the start of a gene on the double helix. 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.
 * Protein Synthesis Review Questions **

What are the steps of translation? mRNA comes into contact with ribosomesRibosomes read the mRNA sequence and converts it into an Amino Acid sequencemRNA sequences are read in sets of three nucleotides. Every three nucleotides codes for one amino acid, called 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 MettRNA molecules transfer the amino acid to the ribosome to the ribosometRNA with a complementary anticodon temporarily binds onto the codonRibosome reads the next codon and another tRNA with a complementary anticodon bindsA peptide bond joins the two amino acids, as the ribosome continues down the mRNA strand the first tRNA falls off, leaving its amino acidRibosome 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 it its function

List three differences between DNA and RNA DNA is deoxyribose and RNA is ribose. In DNA there is T,A,C,G. In RNA there is A,U,C,G.

List the three types of RNA. And state their function (what they do and where they do it)

mRNA- brings a code into cytoplasm for ribosomes to read.

tRNA- transfers amino acid to the ribosome.

rRNA- translates mRNA

What enzyme is used to produce a new strand of RNA?

RNA Polymerase

Which molecule contains the genetic code?

Sequence of nitrogen bases

**Edward Syndrome**
1. Single Gene or Chromosomal Mutation? Chromosomal Mutation

2. Other names? Trisomy 18 or T18

3. Symptoms- Some symptoms include characteristics like kidney malformations, heart defects at birth, small jaw, upturned nose, narrow eyelid folds and widely spaced eyes.

4. Prevalence- 1 in every 6,000

5. Cause- The presence of all or part of an extra 18th chromosome.
