Viruses cannot reproduce. they instead copy themselves with the help of a host cell. a cell can reproduce and doesn’t need help from other cells
They leave their stoma closed during the day and opened during the night. Hope this helps.
The benefits of artificial selection is that you've taken the traits that you desire from a plant or an animal that could benefit your own survival. (Much like our ancestors bred the highest/most efficient crops, leaving us in a good farming position today). However, the drawbacks of artificial selection is that you effectively destroy any natural selection or "survival of the fittest" thus reducing the gene pool. If a virus or bacteria was effective against a crop that we bred, it would destroy our entire farming industry (also works with animals that we breed).
I think the answer is (C). I hope this helps! :)
