Adaptive radiations can be a direct consequence of three of the following four factors. Select the factor that is NOT a direct consequence of adaptive radiation. Select one: a. Genetic drift b. Vacant ecological niches (niches are environment "space" where a particular organism has resources required to survive and reproduce) c. New evolutionary innovations d. Colonization of a new region that contains suitable habitat and few competitor species

Adaptive radiation a. is the result of enriched uranium used in power plants. b. is the evolution of closely related species adapted to use different parts of the environment. c. results from genetic drift. d. is the outcome of stabilizing selection favoring the maintenance of adaptive traits.

Over the past several decades, natural selection has caused populations of Staphylococcus aureus (an infectious wound bacterium) to evolve resistance to most antibiotics. If antibiotic use were stopped, what would you predict would happen to these S. aureus populations? A. Horizontal gene transfer would increase B. The populations will begin colonizing new environments. C. The frequency of resistant forms will definitely increase in these populations. D. They will go extinct without the antibiotic. E. The frequency of nonresistant forms will increase in these populations.
