FoundationIn evolutionary biology, which description best fits an adaptation?
Need a small nudge?

An evolutionary adaptation must be heritable and connected to fitness in an environment.

UnderstandingWhich example is primarily a behavioral adaptation?
Need a small nudge?

Behavioral adaptations involve what an organism does rather than a body structure or biochemical mechanism.

ApplicationWhich plant feature most directly reduces water loss from leaf surfaces in a dry environment?
Need a small nudge?

Look for a feature that creates a barrier to evaporation from the leaf surface.

InterpretationA toxic frog has conspicuous coloration that predators learn to associate with an unpleasant or dangerous encounter. What is the adaptive function of the conspicuous coloration in this case?
Need a small nudge?

The coloration is conspicuous rather than hidden, and predators learn to avoid it.

ConnectionIn a cold region, a mammal population contains heritable variation in fur density. Individuals with denser fur leave more surviving offspring, and the alleles associated with denser fur become more common over many generations. Which conclusion is best supported?
Need a small nudge?

Connect heritable variation, differential reproductive success, and change across generations.
