Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is smaller, a virus or a bacteria?
A
virus
B
bacteria
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Viruses are even smaller than bacteria. They aren’t even a full cell. They are simply genetic material (DNA or RNA) packaged inside of a protein coating. They need to use another cell’s structures to reproduce.

Detailed explanation-2: -Viruses are much smaller. The largest of them are smaller than the smallest bacteria. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.

Detailed explanation-3: -Bacteria are giants when compared to viruses. The smallest bacteria are about 0.4 micron (one millionth of a meter) in diameter while viruses range in size from 0.02 to 0.25 micron.

Detailed explanation-4: -Hence, virus particle is smaller than bacteria.

Detailed explanation-5: -Viruses are the smallest of all the microbes. They are said to be so small that 500 million rhinoviruses (which cause the common cold) could fit on to the head of a pin. They are unique because they are only alive and able to multiply inside the cells of other living things.
