3. 23 males xy and females xx<br />
4. <br />
homozygous, heterozygous, genotype, phenotype, dominant, recessive, allele - see blog post under 3rd nine weeks link<br />
incomplete dominance - the heterozygous genotype shows a blend between the two traits (like mixing paint - red and white make pink)<br />
codominance - the heterozygous genotype produces both traits red and white make red and white stripes or red and white spots.<br />
sex-linked - the gene is found on the x chromosome. Males only get one gene for it and therefore, the traits are more common in males (colorblindness, hemophilia are common examples)<br />
meiosis - division of sex cells or gametes, produces 4 haploid gametes<br />
haploid - half the number of chromosomes<br />
diploid - full set of chromosomes<br />
crossing over - when mother and father chromosomes exchange genes during prophase 1 of meiosis<br />
<br />
5. To do this, know the steps for interpreting a pedigree on your bold print sheet.<br />
6. Review blood type problems from Thursday and Friday<br />
9. We went over all other problems in class except the first pedigree. It is autosomal dominant<br />

Mitosis and Meiosis Comparison<br />
<br />
Mitosis produces 2 cells while meiosis produces 4.<br />
The cells produced in mitosis are identical to the parent while those in meiosis are not.<br />
There are 4 phases in mitosis: prophase, metaphase, anaphase, and telophase. However, meiosis has 8 because each phase happens twice.<br />
Crossing over only occurs in prophase 1 of meiosis.
Chromosome pairs only line up in meiosis 1. During mitosis and during meiosis 2 (which is exactly like mitosis), chromosomes line up singly.
Meiosis produces haploid gametes (sex cells with half the number of chromosomes) while mitosis produces identical cells with the diploid number or full number of chromosomes.<br />
Mitosis has 1 divison while meiosis has 2.<br />
<br />
Mitosis and meiosis are similar in that they are both types of cell divisions. Mitosis and meiosis 2 are exactly the same.

-Direction of movement (down the concentration gradient from more to less OR up the concentration gradient from less to more)<br />
<br />
-Does it require a protein channel or not<br />

If you wish to retake the assessment, read and gain an understanding from the first two links. Use this understanding to attempt the practice problems. Check your answers to see if you are correct.<br />
<br />
Write an explanation for each answer. Tell why it is correct. You should have logical reasoning for each answer and be able to explain it to me when you come in to retake the assessment. The answer key is provided to help you confirm whether or not you are correct. Writing down the answers without doing the problems will not earn you the opportunity to retake the assessment.<br />

<br />
Explain why saltwater fish cannot live in fresh water and why freshwater fish can't live in saltwater. In your answer, use terms such as hypertonic, hypotonic, isotonic, diffusion, and osmosis.<br />
<br />
<br />
<br />
<br />
Dikscuss two situations in which facilitated diffusion would be used instead of simple diffusion.<br />
<br />
<br />
<br />
<br />
<br />
If passive transport does not require energy expediture by the cell, where does the energy come from that moves the molecules?<br />
<br />
<br />
<br />
<br />
<br />
<br />
Answers<br />
<br />
1. Saltwater fish cannot live in freshwater because the freshwater would be hypotonic to the fish. Since there is more salt in the fish water would move in by osmosis causing the fish to swell. Salt would diffuse out in an effort to reach equilibrium.<br />
<br />
Freshwater fish cannot live in saltwater because the saltwater would be hypertonic to the fish. There is a higher concentration of salt in the water than in the fish. Therefore, the water would leave the fish by osmosis resulting in the cells of the fish becoming dehydrated.<br />
<br />
2. If molecules are too big to pass between the phospholipids but small enough to fit through a protein channel, they could use facilitated diffusion. Molecules the size of sugar or amino acids would have to do this. Also, molecules that are polar or have a charge would have to use a protein channel because they cannot get past the lipid tails of the phospholipids. Water and ions would have to use this method for this reason.<br />
<br />
3. The molecules have their own energy. They are constantly in motion, and when they collide, they transfer energy to one another. Therefore, this motion is due to the energy the molecules themselves contain and requires no energy expenditure of the cell.

I am looking forward to working with all of you in the upcoming year. Posted here are several links you will find useful next year. Please download and read the syllabus paying close attention to the grading policy. I have also posted a link to the new Next Generation Science Standards. We will be incorporating these standards in science courses next year. Although some revisions to units will be occurring over the summer, you should browse through the units of study posted on the right of the blog. I will be referring you to the blog frequently for review material, extra practice, homework assignments, and make-up work for students who are absent. It will be your responsibility in the upcoming year to check the blog at least weekly and sometimes more frequently.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-2286823961020687983.post-55999390161037413992012-12-13T11:52:00.007-08:002012-12-13T11:52:59.614-08:00This is a link to an online Biology textbook.
