Textbook QuestionAdd labels to the figure that follows, which illustrates a portion of the human life cycle. 248Has a video solution.
Textbook QuestionA species of rotifer, a small freshwater invertebrate, lost the ability to reproduce sexually millions of years ago. A remarkable feature of its life cycle is the ability to withstand dry conditions. When the rotifer's environment dries out, so does the rotifer, and it can be blown to a new area. Rotifers that land in water will rehydrate and resume an active life. A major pathogen of these rotifers is a species of fungus that cannot survive drying. Some scientists hypothesize that drying rids the rotifers of this pathogen. (a) Design an experimental study to test this hypothesis.258Has a video solution.

(b) Why might the ability to withstand drying reduce any potential advantage of sexual reproduction in this rotifer species?199Has a video solution.
