=Cell Size Lab= 1. Compare and contrast the three cubes after they were sliced in half. The diffusion in three cubes were the same. Both the medium and largest cube cell had a light colored center and dark outside. The smallest was opposite. The inside was darker and the outside was lighter.

2. Which "cell" seemed to be most and least efficient at getting outside substances into the cell? Explain. The cell that seemed most efficient was the smallest cell because the whole cell was purple from the substance getting into it. The cell that was least efficient was the largest cell because it had more white in the middle from the cell not letting the substance into it.

3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? The one of my calculations that seemed to explain my model was all of the cells were the same, but cut different, and the cell didn’t absorb any more or less of the substance.

4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.) Even though a cell is a different size, if it is the same cell and placed in something for the same amount of time, they will all be equal.

="You are what you eat"= I think “You are what you eat” means that if you eat healthy you’re healthy and eat you don’t eat healthy than you aren’t healthy. This means that when you don’t eat healthy, you are usually fatter and if you eat healthy you are usually skinny. If you live on fast food for you entire life you aren’t going to be healthy. One question I have about the foods I eat is are Scalp Potatoes more fattening than mashed potatoes? How will be affected by the things from Mountain Dew if I drink it a lot?

Simple Sugars- Monster was positive because it turned from blue to green to red.

Starches- Monster was negative because there was no starches

Biuret- The monster was negative because it stayed blue.

Sudan 4- The monster was neagtive because it stayed golden brown when I put the product into it

media type="custom" key="25086358" 1. What are the steps of transcription? There are four basic steps of transcription. First, the DNA unwinds as the hydrogen bonds break. Next, the free nucleotides from the RNA pair up with the DNA bases. Next, RNA sugar-phosphate backbone is formed, followed the hydrogen bonding of the untwisted RNA and DNA breaking, leaving the new RNA free. 2. What are the steps of translation? Initiation, Elongation, and Termination 3. List three differences between DNA and RNA. Thymine is replaced with Uracil, RNA is single stranded unlike DNA that is double stranded, and Ribose sugar instead deoxyribose. 4. List the three types of RNA. And state their function (what they do and where they do it) tRNA- transfers RNA; made up of three anticodon; mRNA- Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome rRNA - Ribosomal ribonucleic acid is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms

5. What enzyme is used to produce a new strand of RNA? RNA Polymerase 6. Which molecule contains the genetic code? DNA

 * Intro activity to fuel economy: **

Compare the two graphs below. Write down how the countries compare in **fuel economy** and also in **gasoline taxes**.

Answer the following:
 * 1) What relationships do you notice between the fuel economy and the taxes in a given country? Higher the taxes, higher the field economy
 * 2) Do a quick research of the most often used transportation (types of vehicles) for the countries.
 * 3) What conclusions can we draw? The types of vehicles have affect on the taxes and fuel economy.
