Explanation:

Viruses lack the cellular machinery needed for self-reproduction. They must invade a host cell to hijack its organelles and metabolic processes to replicate their genetic material and assemble new viral particles. Growing/dividing is a characteristic of living cells, mutation is not a requirement for reproduction, and causing epidemics is a potential outcome of spread, not a reproductive necessity.

Answer:

enter a host cell
