BeauA living cell can become a virus factory when a virus infects the cell and co-opts its cellular machinery to replicate itself. The virus uses the cell's resources to make more copies of itself, eventually leading to the cell bursting open and releasing new virus particles to infect other cells. This process can continue, causing the cell to produce vast amounts of viruses.
they target one cell & multiply in it by using its nutrition so cant be caught easily afterwards when the host cell burst & spread in whole body & then very difficult to stop its effect on body
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog’s coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.

Explain why a virus might exist for years and only become active once it comes into contact with a living cell?
A virus can remain dormant for years because it is not a living organism and does not have the ability to replicate on its own. Once it comes into contact with a living cell, the virus can hijack the cell's machinery to replicate itself and cause an infection. The activation of the virus is triggered by specific signals or conditions present in the host cell.
What would happen to a virus that never came in contact with a living cell-?
Since a virus can only replicate on a living cell, host cell, it wouldn't be able to reproduce.
What do a virus and a living cell have in common?
Both a virus and a living cell contain genetic material (either DNA or RNA) that carries instructions for replication and functioning. They both use this genetic material to produce proteins and carry out essential biological processes.
What is the gender of virus?
Viruses do not have a gender. They are microscopic infectious agents that replicate inside living cells.
What kingdom does the variola virus fall in?
The jury is still out on this one, since the existence of viruses became known after the current taxonomical system of classification was devised. In other words, the virus is not currently included in any of the five kingdoms of living matter, these being Anamalia, Plantae, Fungi, Monera and Protista. Also, it is still uncertain at which point a virus becomes living matter, with some researchers professing that the virus is the link between living and non-living matter. Perhaps a sixth kingdom, if has not already been proposed.
