Cold sores are caused by virus.
Describe why a virus such as the cold sore virus cannot be cultured on a nutrient agar plate

Viruses in general require a living host cell for replication. So cold sore virus requires a livng host to replicate. Infected host cells can be cultured and grown, and then the growth medium can be harvested as a source of virus as compared to bacteria that can be cultured in a nutrient agar plate. So ther virus must have a host cell like bacteria, plant or animal in which to live and make more viruses. Outside of a host cell, viruses cannot function.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
