flat =Cell Size Lab= 1. The largest of the cubes, the 3 x 3 x 3, looked like it had the worst results of diffusion rate of the 3 cubes, due to it's size. The 2 x 2 x 2 had the middle of the 3, with a slightly faster diffusion rate. The 1 x 1 x 1 had the best diffusion rate, due to it's small size. All 3 cubes had the solution make it 5mm into the cube, but the size of the cube dictated the diffusion rate. 2. The best cube for getting substances into it was the 1 x 1 x 1. This is because it was the smallest cube, making a substance able to fully penetrate it quicker than a larger cube. The worst cube was the 3 x 3 x 3, because it was the largest, making it take longer for a substance to fully penetrate. 3. I think the distance of diffusion best explained what we observed in our cell models. After taking the distance of diffusion in all cells, we came to realize that all of the cells had the exact same distance, but that same difference altered the rate because of smaller and larger cells. 4. If a cell is smaller, then it will be more efficient at quickly letting substances in and out of it.

=You Are What You Eat= Everyone's heard "you are what you eat", but what does it mean? To me, it means that everything that you put into your body has to be taken out, either as energy or as waste. If all of your energy isn't used, then the excess is put on as body fat, meaning that what you ate became a part of you. I personally want to know how many calories are in the food I eat, and I also wonder what trans fats are.

= Biomolecules in Food Lab = My food I tested was avocados. 1. My food did not contain proteins, carbohydrates or nucleic acid. It did, however, contain fats. 2. Based on nutrition facts, avocado's should only have fats present in them, which was true from the information I gathered from testing. 3. After researching my food in other groups, my results were consistent with the results of other groups.

=Extra Credit Opportunity= Going back to the two questions I asked, being "how many calories are in the food I eat" and "what are trans fats?" After adding up the amount of calories in the 3 days that I put in my food diary, I came to an average amount of 2333 calories. This means that I eat a general amount of 2333 calories per day, answering my first question. Trans fats are generally added to a food to enhance taste in a food, but they can occur naturally in beef and full-fat dairy products. Trans fats start as unsaturated oils, but with the addition of more hydrogen atoms, the double bonds in the oils break and this creates a more stable, solid at room temperature fat. This is bad because the boy doesn't know what to do with the end product after all the bonds are broken, leading to more weight gain.

> RNA polymerase attaches at the TATA box, begins forming the mRNA strand as it reads the template strand of DNA. After the polymerase reaches the end, the mRNA is sent to the ribosomes for translation. > The mRNA enters the ribosomes, where tRNA is matched up with the codons of the mRNA. Whenever this matching occurs, amino acids are released and peptide bonds are formed between the amino acids. Whenever all amino acids are released, they fold in on themselves, forming the tertiary structure of proteins. > DNA is double stranded, RNA is single stranded. > DNA’s sugar is deoxyribose, RNA’s sugar is ribose. > DNA has thymine, RNA has uracil. > mRNA – sends RNA to the ribosomes to be translated, from the nucleus. > tRNA – translates the RNA, found in the ribosomes, releases amino acids. > rRNA – found in the ribosomes, makes up the ribosomes > RNA polymerase > DNA = Fragile X Syndrome = 1. Fragile X Syndrome is a chromosomal mutation. 2. Fragile X Syndrome is also called FRAXA syndrome and Martin-Bell syndrome. 3. Symptoms of Fragile X Syndrome generally relate to learning impairments and cognitive impairment (trouble remembering or learning from experiences). 4. Fragile X Syndrome occurs 1 in every 4000 males and 1 in 8000 females. 5. Mutations in the FMR1 gene causes Fragile X Syndrome.
