Can you explain the difference between a virus and a bacteria?
assistant
A virus is a tiny infectious agent that replicates only inside the living cells of an organism. Unlike bacteria, viruses can only replicate themselves by infecting a host cell and consequently destroying it. Bacteria, on the other hand, are comparatively larger organisms that can live independently outside of the cell, replicating and producing toxins that can cause infection. Bacteria are capable of producing antibiotics to destroy virus, while viruses cannot produce any defense.
