7. Among a migrating species of fish, one individual migrates further than any other in its population. As a result, the fish develops stronger swimming muscles than any other individual in its population, allowing it to catch more prey. Having additional food also allows the fish to lay more eggs. Will the fish's offspring be favored by natural selection? Why or why not?

no

Explanation:

because evolution happens over a very long peroid of time. the muscle of the fish will not be passed to an offspring (think a body builder human does not give birth to a body builder baby)

in a word, a scientific question is testable. a testable question is one that asks about objects, organisms or events found in the world around it
