flat =Cell Size=

1. Compare and contrast the three cubes after they were sliced in half.

The three cubes after they were cut were all colored with pink. Contrasting them the bigger two cubes were colored half a centimeter in and the 1x1x1 cube was colored all the way through.

2., Which “cell”, seemed to be most and least efficient at getting outside substances into the cell? Explain.

The cell that seemed to be most efficient was the smallest cell “smallest cube” because it was colored all the way through and the least efficient cell was the biggest cell “biggest cube” because it was not colored all the way through going in only at half a centimeter.

3. Which of your calculations seems to explain what you observed in your cell models? Why do you think so? The calculations that seemed to explain what I observed in the cell model were the rate of diffusion and distance of diffusion because it was the same in all three sizes of cells (cubes).

4. Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. (Remember: Use an If....., then..... statement.) If the cell is bigger, then the efficiency of something penetrating the cell will be more difficult.

=**You are what you eat**=

The saying “you are what you eat” means to me that everybody should eat healthy. I think this because if you eat fatty foods you will become fat and obese. If you eat healthy as a person and eat in moderation you will be at a healthy weight. I really think this saying is true because people that eat bad foods aren't healthy.

Do vitamins work? What is the least healthy food? What is the healthiest food?

=Food tests= Gelatin test 1: simple sugar negative test 2: starches positive test 3: proteins positive test 4: fats and oils negative

2.The biomolecules that are in gelatin are starches and proteins. In gelatin there are starches. Starches have large numbers of glucose joined together. Proteins are made of one or more chains of amino acids. In gelatin there are proteins. Simple sugars are supposed to be in gelatin but i did not read it. Fats and oils howeve aren't supposed to be in and i have that. http://en.wikipedia.org/wiki/Protein http://en.wikipedia.org/wiki/Starch http://nutritiondata.self.com/facts/sweets/5480/2

3. In really ripe bananas

=**Biomolecules Extra Credit**= The least healthy food that you can eat is a Marie Callendars Chicken pot pie because the calorie count for half the pie is about 530 calories and 11 grams of saturated fats. When you eat all of the pie it over 1,000 calories and 22 grams of saturated fats.The healthiest food that you can eat is a sweet potato because they are a good source of protein fiber and potassium and are loaded with caroentoids. Vitamins do not work because they don't actually give you what they say they give you.

=DNA Replication Powerpoint= media type="custom" key="25077482" =Protein Synthesis Powerpoint= media type="custom" key="25200608"

RNA polymerase unwinds a small portion of DNA, mRNA matches bases of DNA, mRNA breaks away from DNA, and mRNA goes through the nuclear pore to the ribosomes mRNA comes in contact with ribosomes, ribosomes split into a large subunit and a small subunit, ribosomes read the mRNA, and ribosome translate sequence into amino acids to form a protien RNA is single stranded uracil replaces thymine, and ribose rRNA- ribosomal mRNA- messenger tRNA- transport RNA RNA polymerase chromosome
 * Protein Synthesis Review Questions **
 * 1) What are the steps of transcription?
 * 1) What are the steps of translation?
 * 1) List three differences between DNA and RNA
 * 1) List the three types of RNA. And state their function (what they do and where they do it)
 * 1) What enzyme is used to produce a new strand of RNA?
 * 1) Which molecule contains the genetic code?
 * 1) Be sure you can transcribe a gene and determine the complementary amino acids.
 * 2) Be sure you can identify all the parts (see flip book requirement list) of both transcription and translation.

1.Single gene or chromosomal mutation chromosomal mutation 2. Other names Cystic fibrosis of the pancreas Fibrocystic disease of the pancreas Mucoviscidosis Mucoviscidosis of the pancreas Pancreas fibrocystic disease Pancreatic cystic fibrosis 3. Symptoms Salty-tasting skin, which parents notice when they kiss their child Frequent coughing, wheezing, or bouts of pneumonia or sinusitis Difficulty breathing that keeps getting worse Big appetite but poor weight gain Bulky, smelly, greasy bowel movements Over time, the symptoms of cystic fibrosis can worsen and may include: Pancreatitis, a painful inflammation of the pancreas Liver disease Diabetes Gallstones 4.Prevalance 1 and 2500 people 5.Cause caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, on chromosome 7

=Gas Tax and Fuel Economy=
 * 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: The lower the fuel economy the lower the gasoline tax. The ford focus is the most used vehicle in the world People buy cars with good gas mileage
 * 1) What relationships do you notice between the fuel economy and the taxes in a given country?
 * 1) Do a quick research of the most often used transportation (types of vehicles) for the countries.
 * 1) What conclusions can we draw?
