Detailed explanation-1: -Although viruses are not classified as living things, they share two important traits with living things. They have genetic material, and they can evolve.
Detailed explanation-2: -Viruses as living: Have genetic material i.e either DNA or RNA . Can undergo mutation. Show irritability. Are capable to reproduce and hence can increase their number.
Detailed explanation-3: -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.
