Which of the following statements accurately describes the difference between the way bacteria cause disease and the way that viruses cause disease?
Both bacteria and viruses use host cells to reproduce, but viruses kill the host cell immediately, while bacteria maintain life within the host cell indefinitely
Bacteria only cause disease by entering the body through the bloodstream and infecting a host cell, and viruses only cause disease by entering the body through air passages and infecting a host cell.
Bacteria cause disease by incorporating their DNA into the host’s DNA, and viruses cause disease by incorporating their RNA in the host’s RNA.
Bacteria are living cells that grow and reproduce in the body and produce toxins or damage tissues they grow in. Viruses use host cells to reproduce, and these host cells usually die when newly produced virus particles are released.
