Question

which statement best describes how viruses disrupt normal cellular processes to cause disease? a viruses use cell machinery to build products the virus needs. b viruses release large amounts of energy into the cell, causing increased growth rates. c viruses release antibiotics that destroy the cell membrane so more viral particles can be released. d viruses block gene expression and prevent host cell dna replication.

Explanation:

Viruses hijack the cell's machinery for their own replication and other needs. They disrupt normal cellular processes by using the cell's resources such as ribosomes, enzymes etc. for building viral components instead of normal cellular products. Option A describes this process of viruses using cell machinery to build what they need, which disrupts normal cellular processes. Viruses do not release large amounts of energy into the cell to increase growth rates (C is incorrect), they do not release antibiotics (antibiotics are produced by certain bacteria and fungi, not viruses, so B is incorrect), and they do not directly block gene - expression and prevent host - cell DNA replication in the way described in D.

Answer:

A. Viruses use cell machinery to build products the virus needs.
