Which life functions is a virus capable of performing?

Which life functions is a virus capable of performing? Viruses are unique biological entities that are often considered to be on the border between living and non-living. They are obligate intracellular parasites, meaning they cannot carry out life functions independently. A. Viruses do not "feed" in the traditional sense; they lack the metabolic machinery for nutrient uptake and processing. B. While viruses do invade cells and can enter the nucleus to replicate their genetic material, "protecting its DNA" is not a primary life function in the context of what a virus performs* as an active process, but rather a structural aspect of its capsid. C. Viruses cannot grow or reproduce outside of a living host cell because they lack the necessary cellular machinery. D. Viruses can only replicate (reproduce) and assemble new viral particles (a form of "growing" their population) by hijacking the machinery of a living host cell. The final answer is D. Growing and reproducing only when inside a host cell. That's 2 down. 3 left today — send the next one.
