An apple pie has 2 million (2 x 10^6) Staph. aureus cells in it. The food preparer did not wash his hands and probably inoculated the cream with 200 Staph. aureus. He also forgot to refrigerate it. If the pie was made 6 hours ago, how many generations have occurred? How long is each generation? Using the generation 2number of generations x initial number of bacteria = total # of bacteria present after n generations time you calculated, how many bacteria would be present after 8 hours at room temperature

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
