IMMUNOLOGY

Detailed explanation-1: -Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don’t reproduce independently but must replicate by invading living cells.

Detailed explanation-2: -The ability to reproduce is a living characteristic that is observed in viruses. Viruses use the cellular components of the host cell which it infects to reproduce. A genetic material is present inside the viruses like other living organisms.

Detailed explanation-3: -Viruses are considered nonliving because. 1) They cannot reproduce by themselves, 2) they are not made up of cells 3) They cannot carry out metabolism by themselves. The study of Viruses is a part of biology because. They are active inside living cells. Biologists now know that viruses.
