5. Draw a cell with three chromosomes as it moves through mitosis and cytokinesis.

6. Draw a cell with three chromosomes as it move through meiosis and cytokinesis.

7. Why are some cancers heritable and some are not? What is an example of a type of cancer that might be inherited and an example of one that is not?

8. Describe how chemotherapy, radiation, and immunotherapy are used to treat cancer. Describe how cancer cells look and act different than normal cells

9. Describe at least 3 different ways that meiosis and sexual reproduction increases genetic variability in offspring. What advantage does that give sexually reproducing organisms over asexually reproducing organisms? When is asexual reproduction an advantage over sexual reproduction?

10. Explain why there are many more males who are color blind than females. Draw a pedigree to help explain how colorblindness is inherited.

11. Choose a genetic disease/disorder and explain its symptoms and its pattern of inheritance.

10. Describe how an adaptation can become common in a population over time. What conditions must be necessary in order for that to happen? What is the mechanism for that to happen?

11. Describe the similarities and differences between artificial selection and natural selection. Give 2 examples of each.

Compare the parts of the cells to different parts of a college campus.

77) Pain experienced by Dr. Sumida due to an impacted wisdom tooth on the left side of the dentary bone is transmitted via a nerve that enters the lower jaw through the:

76) Which of the following muscles is NOT a muscle of the mandibular arch, innervated by a branch of the trigeminal nerve (V)?

75) In an archaeological cranium, you notice that the internal acoustic meatus of the left petrous temporal bone is almost completely occluded (If you don't know what "occluded" means, you will have to look it up. ) by extra bone growth. The other cranial foramina appear normal. From this you deduce that the individual in question in life may have:

73) Which of the bones listed below is derived from components of the dermatocranium, splanchnocranium, and chondrocranium?

Why is it important to distinguish adaptations from exaptations?

Please provide evidence.

1) Please define the term closed circulatory system. Which animals have it, and what are its’ evolutionary advantages over open systems (why might a closed system be more efficient)?

(10 points)

2) Describe all the events (steps) that occur during a cardiac cycle for mammals (organisms with a

double circulation), as well as the opening and

closing of all heart valves, and the signals arising from the SA and AV nodes. How does this cycle contribute to metabolic homeostasis for our cells, and what is the purpose of the valves?

3) Using information discussed during our lectures thus far, propose 2 physical ways that a human may develop hypertension

(abnormally elevated blood pressure). [One of these mechanisms should

stem from the blood vessels, and the other at the level of the nervous system]. What are the long-

term consequences of elevated hypertension?

1. The sequence above is showing a gene from, which you must transcribed and translated. The promoter (TATA box) is underlined and the start and stop codons are in BOLD. The intervening codons are highlighted. Make predictions about the following mutations:
   1. T is inserted before GTG codon. What’s the resulting protein sequence?
   2. A deletion of A occurs in addition to the insertion in a. What’s the resulting protein sequence?
   3. Do they have a similar effect on the protein? How do they differ?

Imagine that you are observing an enzyme-catalyzed reaction in the laboratory. The reaction is progressing as expected. As you periodically add more enzyme, the reaction increases proportionally until suddenly it stops increasing. At this point, no matter how much more enzyme that you add, the reaction rate does not change. Assuming no other chemicals have been added or changed, explain why the reaction rate has leveled off.

DNA polymerases I, III, and delta have important roles in replication. Which of these proteins have similar functions? Describe those similar functions that they share. Which one performs a different function and what is that function?

44) Your hobby is breeding fancy guinea pigs for people who like that sort of thing. You set up a cross in which the parents are true-breeding and have phenotypes as follows: the father has black fur and a long tail and the mother has white fur and is tailless. They produce offspring in which all of the males are white and have long tails and all of the females are grey with long tails.

a. Is fur color autosomal or sex linked? Explain.

b. Describe which fur color phenotypes are dominant, recessive, co-dominant, or incompletely dominant where appropriate.

c.Is tail length autosomal or sex-linked? Explain.

d.Describe which tail length phenotypes are dominant, recessive, co-dominant, or incompletely dominant where appropriate.

e.What phenotypic ratios do you expect in the F2

Gingivitis is a Periodontal pathogen that causes dental plaques. There are more than 500 species in the oral cavity. A study states that at least 3 genera of bacterial isolates were able to stimulate light production and about 170 were able to respond to the autoinducer AI-2. The signal for AI-2 induces the growth of the bacteria which eventually increases the severity of the infection.

a) Since 170 bacterial isolates respond to AI-2 quorum sensing alone, how many bacterial isolates use:

agr quorum sensing

hsl quorum sensing

AI-2/agr quorum sensing

AI-2/hsl quorum sensing?

b) If AI-2 induces growth and increases the severity of infection, do bacteria that use agr quorum sensing do the same thing or do they differ? What about bacteria that use hsl quorum sensing?

Describe how components of the cytoskeleton, cytoplasm, cell surface and extracellular matrix interact to form cell junctions and the roles of distinct junction types in skin
