Detailed explanation-1: -Viruses lack cellular machinery and hence do not show any characteristics of life until they enter a living body/host and use the host cell to multiply.
Detailed explanation-2: -Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
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.
