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?

In Ms. June’s kindergarten classroom, there are 27 students and three classroom aides. Ms. June instituted a policy in her classroom that if a child yells at another student, they will be given a red bracelet. The red bracelet indicates that the student will not receive attention for 5 mins after they stop yelling at another student. After the 5 mins elapse, the bracelet is removed, and the student can receive attention. What type of punishment procedure is this?

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?

We have collected data and analyzed it to determine whether or not the hypothesis that Earth is currently experiencing a 6th mass extinction is supported. Use the figures provided to complete the following statements: Graph [letter] would be the best graph for determining whether or not we are in a 6th mass extinction, considering the type of data it provides. We can determine if we are currently in a 6th mass extinction by [extinction]. Based on the data provided, our hypothesis is [results].

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]

Male fireflies emit light patterns to attract female fireflies for mating. A group of entomologists is studying the light patterns of closely related but distinct species of fireflies in Ohio. They are investigating what might happen when the ranges of these two species intersect. Which of the following outcomes might they see evidence for in their research?
