It is a biological process that leads a population to have a widespread expression of an advantageous trait.
It is a biological process that leads a population to have a widespread expression of an advantageous trait.

It is a biological process that allows a population to have a competitive advantage in many environmen

Answer 1

The accurate statement about natural selection is:

"It is a biological process that leads a population to have a widespread expression of an advantageous trait."

This statement correctly describes how natural selection works, as advantageous traits become more common in a population over time due to differential survival and reproduction.

Answer 2

Which statement best explains the change in plant population after selection?
Ground-feeding organisms favored short plants, resulting in a taller plant population overall.
High winds reduced the survival rate of tall plants, resulting in a greater range of plant heights.
Plants with narrow stems were more likely to survive than plants with wide stems..
Medium-height plants were favored by conditions that harmed tall and short plants.

Answer 3

The statement that best explains the change in plant population after selection is:

"Medium-height plants were favored by conditions that harmed tall and short plants."

This statement indicates that specific environmental conditions selectively benefited medium-height plants while negatively impacting both taller and shorter plants, leading to a change in the plant population toward greater prevalence of medium-height individuals.
