Which of the following is true of natural selection? Group of answer choices Natural selection works on traits acquired through an organism's lifetime. Natural selection operates at the level of individuals. Natural selection operates at the level of populations.

The correct answer is "Natural selection operates at the level of populations".

Explanation:

One of the most common misunderstandings about natural selection, is that an individual can acquire new traits during its lifetime an "evolve" to survive challenging conditions. This is not true, because natural selection operates at the level of populations by the premise of "survival of the fittest".

The only survivor of the population is the one that makes a bacteria resistant to an antibiotic.
