Which of the following is true of viruses? (2 points) they must use a host cell's metabolic enzymes and pathways to obtain energy. they must use a host cell's ribosomes to synthesize proteins. they must use a host cell's nucleotides for transcription and translation.

All options are true.

Explanation:

Virus may be defined as the small infectious agent that is capable to infect a bacteria as well. Virus needs to enter in the host cell for reproduction and other important biological process.

Virus are also known as intracellular obligate parasite because they use host cell to synthesize their proteins. The virus obtain energy by using the host host cell pathway and metabolic enzymes. The virus use host cell nucleotide for the process of transcription and translation.

Thus, all options are true.
