I think the answer MIGHT be D. RNA synthesis is carried out by proteins known as RNA polymerases that transcribe the genetic information from DNA in a highly-regulated, multi-stage process. But transcribe and translate are different so I'm not a 100% sure. Hope this helps!
Shells are considered biotic because they come from living things. Biotic describes something living or use to be living such as plants and animals. So shells are considered biotic because they come from a living organism.

Eutrophication can result from excess nutrients pollution in bodies of water
The correct answer is stabilizing selection reduces the amount of variation in a trait. disruptive selection increases the amount of variation in a trait.
Stabilizing selection is a type of natural selection in which genetic diversity decreases because natural selection favours an average phenotype and selects against extreme variations.

Disruptive selection is a type of natural selection in which extreme values for a trait are favoured over intermediate values, thus it increases genetic variance.</span>
