= = =Intro Activity to Fuel Economy:= 1. The countries in North America have low taxes compared to the countries over seas. 3. Overall, the most often used transportation is a private car. Which is not very efficient when comparing it to buses and such. =Biomolecules in Foods Lab=

= = The lab results that I have could differ from my research because there might not be enough of the substance to make the test come out positive.

As said before in my lab results, starch can be found in steel cut oats as well as peas (as tested in other groups.) It is used as fuel in the body and any leftovers are stored as fat. Lipids serve to keep heat within an organism/protect the organs or leaves. Steel cut oats have very low levels in this area, while egg yolks do not. When consuming proteins (meat, beans, etc.), you are assured to have an impact on hair, skin and skeletal/cardiac muscle. Last of all are the simple sugars, they can be found in milk and fruit. The body uses them as an energy source. http://www.mynetdiary.com/carbs-in-weight-loss.html http://leavingbio.net/nutrition%20and%20food_files/nutrition%20and%20food.htm

=You Are What You Eat= "You are what you eat" is a saying. Its message is to convince you to eat healthier. The objective is to also educate people with the fact that if you eat a food with more energy or protein your body will ingest those molecules. In the end, the say is attempting to influence your eating habits.

Is this saying true or does society only say this to sell their own products? The saying is true though some commercials bribe their way to get more customers.

=Protists Lab; Euglena=

 =Cell Size Lab= None of the cells were more efficient than the other. This is proven through the fact that each cube was measured 1/2 cm of purple lining the cubes from the inside and these measurements were the same for each size. The only cube that //could// be backed up as most efficient would be the 1x1x1 cm cube because the purple goes the whole way through which it would only be reasonable to see it like that if you put calculations to it. Therefore, if the cube is any smaller than 1x1x1 cm then the solution will go the whole way through the cube by osmosis and if it is larger then the perimeter will have 1/2 cm of the solution around the cube.


 * 1) What are the steps of transcription? Initiation (RNA Polymerase attaches), elongation (RNA strand is being made) and termination (RNA Polymerase meets the end of the strand and falls off).
 * 2) What are the steps of translation? Initiation (mRNA finds the ribosome with the tRNA), elongation (tRNA reads the mRNA) and termination (ribosome falls off at the stop codon).
 * 3) List three differences between DNA and RNA
 * D ** eoxyribose, **R**ibose Thymine, Uracil Double Stranded, Single Stranded Self-Replicating, Synthesized when needed
 * 1) List the three types of RNA. And state their function (what they do and where they do it) mRNA – Carries the message in the DNA for the ribosomes to read (from nucleus to the cytoplasm) tRNA – Transfers amino acid to the ribosome (in the cytoplasm) rRNA – Translates the mRNA (inside of the ribosome)
 * 2) What enzyme is used to produce a new strand of RNA? RNA Polymerase
 * 3) Which molecule contains the genetic code? mRNA
