If antibiotic use were stopped, what would you predict would happen to these S. aureus populations? BL3 (77%) A) They will go extinct without the antibiotic. B) The populations will begin colonizing new environments. C) The frequency of nonresistant forms will increase in these populations. D) The frequency of resistant forms will definitely increase in these populations. 3. Starting from the wild mustard Brassica oleracea , breeders have created the strains known as Brussel sprouts, broccoli, kale, and cabbage. Which of the following statements is supported by this observation? BL2 (71%) A) In this species, there is enough heritable variation to create a variety of features.
