Detailed explanation-1: -Viruses infect all forms of organisms including bacteria, archaea, fungi, plants, and animals.

Detailed explanation-2: -A virus is an infectious agent that can only replicate within a host organism. Viruses can infect a variety of living organisms, including bacteria, plants, and animals.

Detailed explanation-3: -A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are infectious agents with both living and nonliving characteristics.

Detailed explanation-4: -How viruses travel through the body. Once a virus gets into a host’s body, it travels along the surfaces of cells until its proteins begin to bind with receptors on the cells. The virus and the cells then fuse, allowing the DNA or RNA inside the virus to enter the cells, where it begins to reproduce.

Detailed explanation-5: -Based on their host, viruses can be classified into three types, namely, animal viruses, plant viruses, and bacteriophages.
