A. The brightly colored red crabs will leave the area to look for a habitat that does not have any predators that like to eat them B. The brightly colored red crabs will learn to avoid the predators and will not be eaten anymore after subsequent generations. C. Faster bright red crabs will survive longer will reproduce more, and will have more offspring. Over time, the bright red crabs will become faster. D. There will be no change in the behavior of the brightly colored red crabs over time. They will just learn to exist with the predators the way they are.

Answer 1

C. Faster bright red crabs will survive longer will reproduce more, and will have more offspring. Over time, the bright red crabs will become faster.This is an example of natural selection. The brightly colored red crabs that are faster will have a better chance of surviving and reproducing, passing on their traits to their offspring. Over time, the population of bright red crabs will become faster as the slower ones are caught by the nurse sharks.
