A group of 35 sunfish from an initial population of roughly 6,500 sunfish move to a different region where they are entirely reproductively isolated from the original population. They are the only sunfish in the region to which they moved. In the initial population of 6,500, the three alleles for coloration are present in roughly equal proportions. In the population of 35 that moved only two of the alleles for coloration remain. Which of the following most accurately describes this scenario?

The phylogenetic tree below depicts the relationship among a group of mammals called ungulates and an outgroup. The name “ungulate” means “hoofed animal” as ungulates typically have hoofs on their feet and all descended from a common ancestor with hoofs. Use this information and the phylogenetic tree to answer the following three questions.    The trait for hoofed feet is best represented by which letter? [Letter1]. The most recent common ancestor between camel and cow is represented by which letter? [Letter2] According to the tree, which group(s) is/are most closely related to the hippo? [Letter3] Which trait would be an apomorphy? [Letter4] Which trait would be a symplesiomorphy? [Letter5]

In a population of arctic foxes, the thickness of their winter fur is determined entirely by the amount of protein they consume during the autumn months. After a series of unusually cold winters, a new species of high-protein rodent migrates into the area. Foxes that eat these rodents grow significantly thicker fur, which allows them to survive the freezing temperatures better than foxes with thinner fur. How will this population of foxes evolve (in regard to the thick fur phenotype) in response to these colder winters?

A population of geese with a variety of feather colors experiences a drastic reduction in numbers due to their nesting grounds being hit with a tornado. The surviving population of geese happen to have browner feathers than the initial population. The color of feathers is genetically determined, which means that the tornado led to what type of effect on the geese population?

cumulative The Kb of a monoprotic, weak base is 5.7*10-4. What is the equilibrium hydroxide concentration of a 1.4 M solution of the weak base? Use the small-x approximation if possible. Answer in M. Do not type units. Do not use scientific notation.

List FIVE (5) strategies that a person can use to identify aspects of a healthy relationship and support each of these strategies with a quote from Donatelle. The point before the quote should be a FULL sentence. Additionally, the quote should strengthen or expand on your point and NOT just be a repeat of your point.  For example (as a reminder, you may NOT use the example answer as part of your answer): You respect the “unique” aspects in the person. Donatelle states, “you respect each other’s individuality, embrace each others differences, and allow each other to be ‘yourselves'” (164).
