Question

which of the following describes an adaptation? choose 1 answer: a the learned ability of a chimpanzee to use moss as a sponge to soak up water for drinking b light brown fur in a rodent, which allows it to stand out against the newly formed black lava rock in its environment c thin, hollow bones in a bird, which make the bird’s skeleton lighter for flying

Explanation:

To determine an adaptation, we recall that an adaptation is a trait (structural, behavioral, or physiological) that enhances an organism's survival/reproduction.

• Option A: A learned behavior (using moss as a sponge) is not an adaptation (adaptations are inherited, not learned).
• Option B: Light brown fur that makes a rodent stand out against black lava rock would reduce survival (not an adaptation, as it hinders camouflage).
• Option C: Thin, hollow bones in birds are a structural adaptation inherited to reduce weight for flying, aiding survival.

Answer:

C. thin, hollow bones in a bird, which make the bird’s skeleton lighter for flying
