A gram-positive bacteria has entered through a cut. Describe IN DETAIL how an inflammatory response would work against this bacteria.

What 3 viruses can cause a common cold?

Briefly describe life- cycle. Include replication and viral release.

Describe how the central chemoreceptors act to regulate ventilation. Be sure to describe the integrating centers and sensors involved, their locations, and explain their roles in determining ventilation rate. Be sure to include any chemical equations (and enzymes!) that are necessary to explain ventilation regulation and explain how the mechanisms work. Then explain how the system responds when arterial blood pH is elevated, and explain how the response corrects arterial CO₂. Explain how the system responds when arterial blood pH is decreased, and explain how the response corrects arterial CO₂.

Describe how the peripheral chemoreceptors act to regulate ventilation. Be sure to name the sensors involved, their locations, and explain their roles. Be sure to include the molecules sensed, and any chemical equations (and enzymes!) that are necessary to explain their roles. Then explain how and when the system acts to increase ventilation. Explain how and when the system acts to decrease ventilation.

33. Describe an experiment in which you would use replica plating using the following prompts: ( 10 total)

1. What is the question you are trying to answer that would require replica plating?

2. What tools do you need? ( bacterial strains, types of agar, nutrients, etc)

3. Why do you need to use replica plating instead of regular plating?

4. What are you expected results?

5. Is this an example of direct selection or indirect selection? Explain.

What is the functional consequence of the following (Information presented is complete)

A.) Mutation that inhibits the expression of all t-SNARES in a cell

B.) Mutation that makes all ER targetinf signal sewuences C-terminal instead of N-termina

C.) Mutation of RTKs that inactivates the kinase domain

D.) What is the consequence of G that binds a non-hydrolyzable GTP?

E.) What is the consequence if uniquitin lysines are all mutated to tyrosines?

How does the human cardiovascular system respond when an individual faces a fight-or-flight situation? (1 point)

a)Blood pressure and heart rate decrease, and blood supply to large muscle groups increases.

b)Blood pressure and heart rate increase, and blood supply to large muscle groups is increased.

c)It slows down and diverts blood flow to the brain, providing more energy for problem solving.

d)It speeds up and diverts blood flow to the digestive system, providing additional energy.

Describe how information is passed from the pre-synaptic to post-synaptic neuron in order to allow information flow throughout the nervous system.

An Iron Man competition takes over 8 hours to complete.

The following are some of the changes that occur to the human body during exercise:

i. increased body temperature
ii. loss of H₂O and electrolytes
iii. decreased blood pressure

How does a human body adjust to this prolonged changes during exercise (provided above) to maintain homeostasis?

What happened to the adaptive landscape of Daphne over the last years of the study? How does this change relate to hybridization, and how and why do species normally guard against hybridization?

1. Genes often interact with one another. The term epistasis is applied to cases in which one gene alters the expression of another gene that is independently inherited. In Labrador retriever dogs one gene locus is involved with production of melanin pigment: B (black) and b (brown) are its two alleles. Another gene locus determines whether the melanin produced is actually deposited in individual hairs as they grow (E) or not deposited (e). Any dog with at least one dominant allele B and one dominant allele E will be a black Labrador. A dog with the homozygous recessive bb and at least one dominant E will be a lighter, chocolate Labrador. If a dog has the homozygous ee genotype it will be a yellow Labrador, regardless of the alleles at the pigment locus.

   1. Give possible genotypes for a dog with the black Labrador phenotype?

      With respect to locus B

      With respect to locus E

   2. Give possible genotypes for a dog with the chocolate Labrador phenotype?

      With respect to locus B

      With respect to locus E

   3. Give possible genotypes for a dog with the yellow Labrador phenotype?

      With respect to locus B

      With respect to locus E

2. A yellow Labrador with the genotype bbee mates with a black Labrador that is homozygous for both alleles. What are the ratios of genotypes and phenotypes expected in the F1 and F2 generations?
