Question

which of the following functions of living organisms can be carried out by viruses, and which require the help of the host cell? metabolize and use energy use nucleic acid (like dna) as the genetic material maintain internal homeostasis reproduce

Explanation:

Viruses cannot metabolize and use energy on their own, nor maintain internal homeostasis, so these require host - cell help. Viruses use nucleic acid (DNA or RNA) as genetic material on their own. Reproduction requires the machinery of the host cell.

Answer:

metabolize and use energy: host
use nucleic acid (like DNA) as the genetic material: virus
maintain internal homeostasis: host
reproduce: host
