The serengeti region of africa contains a population of cheetahs and a population of lions. studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. the cheetah population is also much smaller than the lion population. both populations are vulnerable to infection with a particular virus that can be fatal in both species. what is the most likely outcome if both populations are infected with this virus?

a. the cheetah population is more likely to survive because there are fewer individuals for the virus to attack.

b. the cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses.

c. the lion population is more likely to survive because larger populations are immune to viruses.

d. the lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.

Ms. w, a 21-year-old woman, came into a clinic after suffering a deep laceration on her foot while walking barefoot around her yard. the wound was cleaned, sutured, and bandaged, and she was released to return home after receiving tetanus antitoxoid. within 72 hours, the wound area was red and swollen, the suture line was dark in color, and it was accompanied by severe throbbing pain. ms. w had a high fever, her heart felt like it was racing, and she was finding it hard to concentraten even on simple tasks. she returned to the clinic and was immediately taken to the hospital. following lab tests, a diagnosis of acute necrotizing fasciitis was made. discussion questions 1. explain why ms. w. received a tetanus antitoxoid before leaving the hospital. (see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?
