Question 7 • FL-2002040-M/J Comprehensive Science 1 A-CR

Which statement contrasts viruses and bacteria?

Answer
A
Viruses release toxins to destroy cells, while bacteria replicate inside cells.
B
Viruses can replicate inside cells, while bacteria release toxins to destroy cells.
C
Both bacteria and viruses must replicate inside a cell.
D
Neither viruses nor bacteria can produce toxins.

Explanation

Viruses must enter a host cell to reproduce, using the cell’s machinery. Some bacteria release toxins that damage or kill cells, but bacteria can also reproduce on their own rather than requiring a host cell. Therefore, the correct contrast is that viruses replicate inside cells while bacteria may release toxins.
