Question

select the correct answer. which scenario is an example of a functional adaptation? a. a male bird lets out a mating call to attract a female bird. b. poison dart frogs produce a toxic venom that they can secrete out of their skin. c. cobras elongate their bodies and hiss when theyre threatened. d. the color and shape of a flounder allow it to camouflage itself on the sea floor.

Explanation:

To determine the correct answer, we analyze each option based on the definition of functional adaptation (a physiological or biochemical trait that helps an organism survive/reproduce).

• Option A: A mating call is a behavioral adaptation (action), not functional.
• Option B: Producing and secreting toxic venom is a physiological/biochemical function that deters predators, fitting functional adaptation.
• Option C: Elongating body and hissing is behavioral (action), not functional.
• Option D: Color/shape for camouflage is a structural adaptation (physical feature), not functional.

Answer:

B. Poison dart frogs produce a toxic venom that they can secrete out of their skin.
