15The hypothesis that within-host selection favors higher virulence assumes that

- Bmetabolism is plastic
- Ctraits such storing fat in the abdomen are adaptive under certain circumstances
- Dall
18Pathogens evolve rapidly because

- Cantibiotic resistance is common
19Selection within pathogen hosts typically favors _____; selection across hosts favors _____.

20The hygiene hypothesis assumes that
- Aa lack of hygiene increases rates of allergies and autoimmune diseases
- Bthe environment experienced by many modern human societies is much different from the environment experience over most of our evolutionary history

26In the paper wasp, although all females in a nest are physiologically capable of reproducing, a single female monopolizes almost all reproduction, while other females help rear her offspring. In some nests, female helpers are unrelated to the reproducing female. The most likely explanation for this is that these helpers gain _________ benefits, such as ____________.
- Aindirect; an increase in the reproductive output of the reproducing female
- Bdirect; an increase in the reproductive output of the reproducing female
- Cdirect; possibility of taking over the reproductive role when the reproducing female dies
- Dindirect; possibility of taking over the reproductive role when the reproducing female dies
