Question

what are adaptations? those features of an organism that help it survive changes in things like rainfall, sunlight, or temperature the size of a population when things are going well for it

Explanation:

To determine the correct definition of adaptations, we analyze each option:

• The first option, "those features of an organism that help it survive", aligns with the biological concept of adaptations. Adaptations are structural, physiological, or behavioral traits that enhance an organism's ability to survive and reproduce in its environment.
• The second option, "changes in things like rainfall, sunlight, or temperature", describes environmental changes (abiotic factors) rather than adaptations of an organism.
• The third option, "the size of a population when things are going well for it", refers to population growth or carrying capacity, not adaptations.

Answer:

those features of an organism that help it survive
