Viruses
A virus is a microscopic infectious agent that replicates only inside the living cells of an organism. Viruses are not living organisms as they cannot reproduce or carry out metabolic activities outside a host cell.
Incorrect statement:
C) Viruses can perform all of their metabolic activities except reproduction when outside a living host.
Explanation:
Viruses are not capable of performing any metabolic activities outside a living host cell. They cannot carry out functions such as respiration, digestion, or synthesis of proteins or nucleic acids. The only function they can carry out outside a host cell is attaching to and infecting a host cell.
Correct statements:
A) Viruses are acellular.
B) Viruses are smaller than bacterium.
D) Viruses are non-living organisms.
Explanation:
A) Viruses are acellular, which means they do not have a cellular structure and do not contain any organelles such as mitochondria, ribosomes, or nucleus.
B) Viruses are smaller than bacteria. Bacteria are typically between 0.5 and 5 micrometers in size, while viruses are usually between 20 and 300 nanometers in size.
D) Viruses are non-living organisms as they do not have the properties of living organisms such as metabolism, growth, or reproduction outside a host cell. They cannot maintain homeostasis, respond to stimuli or evolve.

Viruses are inert crystalline structures with an exclusive property of polymorphism. They are acellular so metabolism is not possible. They can only replicate inside the host. They generally dominate over protein machinery of the host to derive their nutrition.
