While taking a field class in Panama, you observe two populations of beetles that look similar, but have some morphological differences. The beetles also appear to live in slightly different parts of the forest (under logs vs. on vegetation). Your instructor takes a look at the beetles and feels that they may actually be different species. In looking through the literature, you only find the description of the beetles that live under the logs and not the ones you found in the vegetation. Your instructor suggests that you design a project to test whether the beetles are the same or different species. How would you design an experiment to test this question? What evidence would you need to support the hypothesis that the beetles are different species?

A biologist is studying three species of small fish (sp 1, sp 2, and sp 3) that cling to the bodies of bigger fish and consume their parasites. She conducts an experiment with three treatments. In each treatment, she removes a different one of the small fish species and examines the number offspring produced by the large fish. Which of the following conclusions are supported by the data shown in the figure?
