Detailed explanation-1: -Which of the following provides the most significant support for the idea that viruses are nonliving chemicals? They cannot reproduce themselves outside of a host. Which of the following is not true about spikes? They are used for penetration.
Detailed explanation-2: -Outside of a host cell, viruses do not use any energy. They only become active when they come into contact with a host cell. Once activated, they use the host cell’s energy and tools to make more viruses. Because they do not use their own energy, some scientists do not consider them alive.
Detailed explanation-3: -They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell. Therefore, viruses are obligate intracellular parasites. According to a stringent definition of life, they are nonliving.
Detailed explanation-4: -Viruses are considered as something between living and non-living because they do not grow or reproduce by themselves. This makes them non-living.
