5-8 different features of the native PNW Temperate evergreen forest biome.

Which of the following represents an example of coevolution?

Group of answer choices

Over time, peppered moths shift from having mostly light-colored wings to mostly dark-colored wings.

The majority of human babies are born weighing between 5.5 and 10 lbs.

The flower of the plant species, Centropogon nigricans, is exclusively pollinated by the tube-lipped nectar bat, Anoura fistulata. The bat has the longest tongue relative to its body length of any mammal and it uses its long tongue to reach the nectar inside of the long, thin C. nigricans flower.

Dark mice on lava and light mice on sand are predated upon less than gray mice in either habitat.

The greenhouse effect:

Group of answer choices

A) has caused extreme fluctuations in climate over the past thousand years.

B) causes seasonal differences in day length every year.

C) is primarily caused by humans through burning of fossil fuels and deforestation.

D) is caused by atmospheric gases that trap heat in the Earth’s atmosphere.

E) is synonymous with global climate change – they mean the same thing.

Describe how and when peptidoglycan synthesis is inhibited by the antimicrobials.

Discuss the role of Ixodes scapularis and Ixodes pacificus in Lyme disease.

A frame shift mutation

a. can lead to a longer protein

b. can lead to a shorter protein

c. does not change the resulting protein

d. changes the way codons are read by the ribosomes

e. changes the way codons are read by the ribosomes and can lead to a longer or shorter protein

3. Assume that in humans, right-handedness (R) is dominant over left-handedness (r). A left handed man marries a right-handed woman. They have ten children all right-handed. What are the genotypes of all individuals of this family? Dad = Mom = Kids =,

4. A right-handed man marries a left-handed woman. Their first child is left-handed. What are the chances that future children will be right-handed? _________% Left-handed?________%

5. Assume in humans that brown eyes (B) are dominant to blue (b) and right-handedness (R) is dominant over left-handedness (r). A brown-eyed, right-handed man marries a blue-eyed right handed woman and their first child is blue-eyed and left-handed. What are the genotypes of the two parents?

Mom _________

Dad __________

6. In humans, a type of blindness called aniridia (B) is dominant over the normal sighted individual (b). Migraine headache (M) is the result of a different dominant gene. A non-migraining man with aniridia whose mother was not blind marries a normal sighted woman who suffers from migraines but whose father did not. In what proportion of their children would you expect to have both aniridia and migraine to occur? __________

   7. A researcher believes, as a result of investigation, that the dark pigmented skin of the pure African is due to two pairs of factors, and that white skin is due to the absence of these factors. Let these factors be represented by AABB and the white skin by aabb. Since no skin is pure white (even in winter!). Assume that A = 30% of black, B = 20%, a = 2%, and b = 1%.

Now cross two individuals both with the genotype AaBb. List the percent of color and the number of individuals in each as the result of such a cross.

Select two diseases that involve different arthropod vectors in their

epidemiology. Discuss each disease and describe the role of each vector in the life cycle of the pathogen and establishment of the disease.
