EVERYDAY SCIENCE

Detailed explanation-1: -Viruses are considered as something between living and non-living because they do not grow or reproduce by themselves. This makes them non-living.

Detailed explanation-2: -Living things use energy. 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: -Viruses are microscopic parasites responsible for a host of familiar – and often fatal – diseases, including … the flu, Ebola, measles and HIV. They are made up of DNA or RNA encapsulated in a protein shell and can only survive and replicate inside a living host, which could be any organism on earth.
