Question

Which statement describes an effect of natural

selection on a species?
(1) It favors the survival of certain members
of the species and results in a change in
the proportion of individuals with highly
adaptive traits.
(2) It provides feedback mechanisms for members
of a species and results in a change in the
proportion of individuals with homeostatic
controls.
(3) It leads to reproduction with other species,
increasing the number of different adaptations.
(4) It increases competition between populations
that occupy different niches, increasing the
chance of extinction of the less-adapted
species.

Answer 1

The statement which correctly describes natural selection is (1) it favors the survival of certain members of the species and results in a change in the proportion of individuals with highly adaptive traits.

Natural selection, by definition talks about the successful passing down of genes from older generations to younger generations. These then are better adapted to their environment. This is exactly what the first answer is about.
