flat =Characte == ristics of Life= What is life? -Life is when something is functioning properly and contains at least one cell. Cells must be working correctly in order for something to be living.

What does it mean to be living? -To be living is to have your body functioning correctly and the parts of your body working together like they should.

=Cell Size Lab=

1. The three cubes, once sliced in half, looked both similar and different. The largest cube and the middle cube looked most alike apart from the smallest because the solution penetrates each cube five millimeters, so on the smallest, you could not see a white center where the solution did not penetrate. Its size let the solution penetrate the whole way through. On the other two, which are both larger than five millimeters, you can see where the solution could not reach, which is the white center. 2. The “cell” that seemed most inefficient in getting outside substances into it was the largest one. The solution only penetrates the “cells” five millimeters, and because the largest one is much over five millimeters, it left a lot of it untouched by the solution. The middle “cell” is slightly more efficient, and finally, the smallest one is the most efficient. 3. I believe that the distance of diffusion formula best explained how I observed the “cell”. I think this because with this formula, you can tell how far the purple solution can penetrate, which is five millimeters. You can see on the largest and medium sized “cell” the white center where the solution could not penetrate. On the smallest, however, the solution penetrates the whole thing. 4. If the cell is small, then it is more efficient in getting substances into and out of it.

=Protists=


 * Euglena**

==

Facts:

Euglena can live in both freshwater as well as saltwater, which is something that most organisms cannot do.

The bright green body of the Euglena is a result of the number of chloroplasts within them.

Also, Euglena is both autotrophic and heterotrophic, which means that it can produce its own food as well as consume food from it's environment.

=You Are What You Eat=

The saying “you are what you eat” means that if you eat healthy foods most of the time, then you will be a healthy person. At the same time, if you eat unhealthy foods most of the time, you will be an unhealthy person. Your health is greatly determined by the food that you eat.

3. When compared to other group's foods, my data from beef came out mostly consistent in comparison to The Fire Breathing Giraffes, which also had beef.

=Biomolecule Extra Credit=

My questions in You Are What You Eat are:

1. What is high fructose corn syrup?

High fructose corn syrup is a common sweetener made out of corn and is used in many foods and drinks. Use of high fructose corn syrup use has also increased in recent years. It is comprised of either 42% or 55% fructose, and the remaining sugars are glucose and others. High fructose corn syrup is also very similar to table sugar based on its composition. Also, fructose is a simple sugar often found in fruits and honeys.

2. How is high fructose corn syrup bad for your body?

As a result of the increased use of high fructose corn syrup, more obesity and related cases have been occurring. Though it is closely related to table sugar, it is still different and your body will react to it differently. Overall, high fructose corn syrup is not extremely bad for you, with the exception being eating foods with too much of it.

3. What is a trans fat?

Trans fat is made by adding hydrogen to vegetable oil through hydrogenation, making it man-made. Trans fats help preserve foods longer and help keep foods from being as greasy. Trans fat is also known by the term "partially hydrogenated." Overall, trans fat is not healthy and should be consumed in small amounts, mostly because it is not natural.

=Protein Synthesis Review Questions=

1. What are the steps of transcription? DNA is transcribed by RNA polymerase Nucleotide sequences tell RNA polymerase where to begin and end RNA polymerase attaches to the promoter region 2. What are the steps of translation? Initiation, Elongation, Termination 3. List three differences between DNA and RNA- DNA is double-stranded helix, RNA is single stranded DNA is composed of deoxyribose, RNA is composed of ribose DNA has Thymine as a pairing to Adenine, RNA has Uracil in place of Thymine as a pairing to Adenine. 4. List the three types of RNA. And state their function (what they do and where they do it)- mRNA- messenger strand (cell nucleus), tRNA- moves amino acids (in cytoplasm), rRNA translates mRNA into proteins (in ribosome) 5. What enzyme is used to produce a new strand of RNA? RNA Polymerase 6. Which molecule contains the genetic code? tRNA 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

Fuel Economy Questions

1. The lower the fuel economy, the lower the taxes. 2. The most popular form of transportation in the US are SUVs, in contrast to more compact vehicles in Asia. 3. We can conclude that for the lower gas taxes we have, the lower fuel economy we will get.
