Question

URGENT!!!

A biology class observed that a species of cactus plant was adapted
to store water and survive in a dry climate.

Which factor is responsible for this population of cactus plants
becoming well-adapted to its environment?

Select one:
O random changes in allele frequency in every generation

O lack of genetic variation among individuals

O migration of gametes into the population

O unequal success of individuals in surviving and reproducing

Answer 1

O unequal success of individuals in surviving and reproducing (natural selection)

Natural selection is the process by which certain traits become more or less common in a population over time due to the differential survival and reproduction of individuals with those traits, which leads to the adaptation of species to their environment.
