Viruses are how much smaller than bacteria?
Correct answer: B. 10 to 1000 times
- A. 20 to 2000 times
- B. 10 to 1000 times
- C. 500 times
- D. 3000 times
Explanation
A virus ranges in size from 20-250 nanometers making them about a hundred times smaller than most bacteria. Since viruses are almost a hundred times smaller than most bacteria, they lie in this range hence this option is correct.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
