MCQ IN MEDICINE

Detailed explanation-1: -Viruses are tiny infectious agents that rely on living cells to multiply. They may use an animal, plant, or bacteria host to survive and reproduce. As such, there is some debate as to whether or not viruses should be considered living organisms. A virus that is outside of a host cell is known as a virion.

Detailed explanation-2: -Viruses are really, really, small (even 100x smaller than bacteria!) pathogens that can only replicate within a living organism, called a host.

Detailed explanation-3: -Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
