Goryan [66]

Answer:

B) Natural selection favored rabbits that were resistant to the virus

Explanation:

Most likely, virus resistance occurred over time, as a consequence of mutation. Individuals that carried the resistance mutation become favourable by natural selection.

Natural selection is evolutionary mechanism which favours traits of an organism that help him survive and reproduce (increase organism's fitness). In the example above, resistant rabbits that survived had the favorable trait (resistance) by natural selection.

The answer is B: Response to stimuli
what response to stimuli means is that the organism reacts to something around it
the venus flytrap wouldn't just randomly close for no reason

unless your teacher is referring to absorbing the nutrients of the dead fly after it's been killed
but I don't think that's what this question is about
