Question

natural selection is a process by which organisms that are better adapted to their environment tend to
increase in size,
migrate,
evolve new traits.
survive.

Explanation:

To solve this, we analyze each option:

• "increase in size": Natural selection isn't about size increase; organisms adapt, not just grow larger.
• "migrate": Migration is movement, not the result of natural selection's adaptation - driven process.
• "evolve new traits": Natural selection acts on existing traits, favoring those that aid survival; new traits come from mutations, not direct evolution via selection.
• "survive": Natural selection is the process where better - adapted organisms are more likely to survive (and reproduce), as their adaptations help them cope with the environment.

Answer:

D. survive
