Which of the following affects natural selection?

Changes to the environment
A small gene pool
Antibiotics
All of the above

Explanation

Answer: D - Natural selection is nature’s way of selecting which organisms survive. Changes to the environment can make an organism prosper or kill it off. A small gene pool can do the same. Antibiotics kill some bacteria, while remaining bacteria thrive and mutate, making the bacteria stronger and more resistant to antibiotics.
