repel competitor males, then the data would fit which type of sexual selection ? a) Intersexual selection d) male-male intimidation model b) Intrasexual selection e) Both answers (b) and (d) are correct c) Material benefits model 25) Bateman’s experiments with fruit flies indicated that in this species, Consider an experiment in which a large population of bacteria was stored in a freezer (which does not harm the bacteria). On the first day of the experiment a sample of the bacteria was taken from the freezer, thawed, and infected with a virus. On the next day the progeny from the virus was collected and used to infect a new sample of bacteria from the freezer. This procedure was continued each day for 2 weeks. The virus rarely kills the bacteria but it does slow reproduction of the bacteria by causing it to make virus progeny in addition to carrying out its own reproduction. Virus that reduce the fitness of the bacteria more have higher fitness because they produce more offspring. 26) The level of harm (fitness reduction) caused by the virus to the bacteria: 27) Consider the coevolution between the Yucca moth and the Yucca plant. If a new mutation in the moth permitted it to produce eggs and larvae that were undetectable by the plant, then:

28) Consider the coevolution between the lysine protein expressed in sperm and the matrix protein that surrounds the abalone egg. If the egg matrix protein were coevolving with a pathogen that gains entry to the egg by boring through the matrix, then: a) The egg matrix protein is expected to evolve rapidly due to the interspecific Red-queen process b) The lysine protein is expected to evolve rapidly c) The bacteria will evolve rapidly due to the intraspecific Red-Queen process d) Answers (a) and (b) are correct e) Answers (a), (b), and (c) are all correct

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
