question 11 of 25
what is an adaptation?
a. a genetic mutation that harms an organism
b. a trait that makes an organism more likely to reproduce
c. something that an organism learns during its life
d. a way for an ecosystem to recover after a disturbance

Explanation:

An adaptation is a trait that has evolved through natural selection. Traits that enhance an organism's ability to survive and reproduce (fitness) are favored. Option A is incorrect as adaptations are beneficial, not harmful. Option C refers to learned behaviors (not adaptations which are often heritable traits). Option D is about ecosystem recovery (not an organism - level trait). Adaptations increase an organism's reproductive success.

Answer:

B. A trait that makes an organism more likely to reproduce
