Question

Over time, why does natural selection continue to work? A.) Environments are always changing B.) Animals are continually mating. C.) Organisms are always improving. D.) Genes are constantly mutating.

Answer 1

A
I would say because natural selection selects the traits that would help the organism survive in their environment.

Answer 2

Answer:

The correct answer would be A.) Environments are always changing.

Natural selection is one of the natural phenomenons which causes the evolution of the organisms.

By this phenomenon, the organisms which are better suited to the changing environment tend to survive and reproduce at a better rate as compared to the organisms which are less adaptive to the environment.

Natural selection mainly depends on the environment (such as temperature, pressure, color et cetera) and thus, it continues to work as the environment keeps on changing.

For example, the temperature and levels of oceans are increasing due to global warming, so, the marine organisms which are better adapted to the changing temperature, pressure, and salinity would survive and reproduce more.
