flat =Cell Size Lab= 1.) Compare and contrast the three cubes after they were sliced in half. The cubes were similar because they all had the same diffusion rate as each other. They were different because the smaller the cube the more of the inside that the substance covered. 2.) Which “cell” seemed to be most and least effective at getting outside substances inside the cell? Explain The biggest cube seemed to be the least effective because there was still a lot of agar that still did not have the substance diffused into it. The smallest cube seemed to be the most effective because there was little to no agar with out any of the substance diffused into it. 3.) Which of your calculations seems to explain what you observed in your cell models? Why do you think so? The calculation of rate of diffusion explains what I observed because it showed how far the diffused substance got into the cell 4.) Speculate on a relationship between cell size and efficiency. Your statement should resemble a hypothesis. If the cell is smaller then the more efficient the cell will be.

=Protist Lab= //Blepharisma// 1. Blepharisma for the most part feed on algae. 2. It takes thousands of cilia to move. 3. Some feed off of animal fur Facts found on @http://poster.4teachers.org/view/poster.php?poster_id=204828

=You are what you eat= The saying you are what you eat means many things to me. One is what is obvious said. It says if you only eat unhealthy foods that means you will be unhealthy yourself, and if you eat healthy foods you will be healthy. Both can be wrong at the same time, so the saying can also mean nothing to me. People can eat some of the healthiest foods ever and still be unhealthy. People can also eat unhealthy foods and still be healthy. I have come to find that being healthy or unhealthy don’t just deal with food. Someone’s health depends on many other factors like exercise and the type of nutrients that are taken from what they eat. I have several questions. What foods are actually naturally made foods that are unhealthy for you? Why do scientists go back and forth with foods saying one day they are healthy and the next saying they are unhealthy? Are their any ways to prepare unhealthy foods to make them healthy?

=Protein Synthesis Review Questions= 1. The Double Helix of DNA unwinds as the hydrogen bonds between the bases of the two 'poly nucleotide' strands are broken down. Enzymes are used. One strand is used as a template to copy DNA "sense strand" Free mono nucleotides lying free in the nucleus line up along the sense strand by specific base pairing. Condensation reaction links up the mono nucleotides into a poly nucleotide strand. The new strand formed is a messenger RNA. It then moves out of the nucleus through the nuclear poles heading for the ribosomes ready for translation. The DNA strands regain there hydrogen bonds and coil int a double helix again unaltered.

2. During translation, the amino acid detaches from the transfer RNA molecule and attaches to the end of a growing protein chain when the ribosomal RNA anticodon binds to the messenger RNA codon the transfer RNA anticodon binds to the messenger RNA codon. A "stop" codon is encountered. The protein chain sends a signal through the nerve cells to the brain.

3. DNA is double-stranded helix, RNA is single stranded helix. DNA is composed of deoxyribose sugar, RNA is composed of ribose sugar. DNA has Thymine as a pairing to Adenine, RNA has Uracil in place of Thymine as a pairing to Adenine.

4. mRNA - is used to move the information contained in DNA to the ribosome for copying. tRNA - it transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA. The amino acids then can be joined together and processed to make polypeptides and proteins. rRNA - is located in the cytoplasm of a cell, where ribosomes are found. rRNA directs the translation of mRNA into proteins.

5. RNA polymerase

= DiGeorge Syndrome = 1. DiGeorge Syndrome is a single gene mutation. 2. Other names for Digeorge are Velocardiofacial syndrome, 22q11.2 deletion syndrome, 22q11.2 deletion syndrome, or Cayler Cardiofacial syndrome. 3.
