Meerkats are small desert mammals that live in groups of 20-50 animals. you observe one meerkat standing upright on a stump, looking around, while other meerkats forage for food. you hypothesize that this is an example of kin selection. what additional information would you need to know to evaluate your hypothesis?
a. the body size of this meerkat relative to other members of the group
b. the gender of this meerkat as well as that of all other members of the group
c. the degree of genetic relatedness of this meerkat to all members of the group
d. all other activities of this meerkat as well as those of all other members of the group
e. the foraging success of this meerkat as well as that of all other members of the group

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?
