Question

A virus is unlike an organism in that the virus is __________.

Answer 1

A virus is unlike an organism in that the virus cannot reproduce outside a living cell.
Organisms can reproduce independently, whereas viruses have to "kidnap" other cells and settle there in order to make an "offspring."

Answer 2

A virus is different from all other organisms because it can not be classified as living or non-living thing. It only becomes a living thing when it attaches itself to a living organism. When it is alone, it remains dormant until it invade a living system. It can only becomes active when it enter a living system.
