Viruses can infect all forms of life and are found anywhere there are cells, including in soil, water, and air. Viruses lie dormant until entering a host cell, usually through the nose, mouth or breaks in the skin. Once inside a host cell, the virus attaches and releases its genetic material, hijacking the cell's enzymes to produce new virus particles which then break free and infect other cells. Viruses are considered by some scientists to be both living and non-living, as they are inactive particles outside of a host cell but become active reproducers inside a living cell.

All the five kingdoms are made up of cells which is the basic
unit of life.

5. Where are they found?
Viruses are found on or in just about every material and
environment on Earth from soil to water to air. They're
basically found anywhere there are cells to infect. Viruses
have evolved to infect every form of life, from animal to
plant and from fungi to bacteria.

8. How does virus infect you?
Viruses lie around our environment all of the time just waiting for a host
cell to come along. They can enter us throughthe nose, mouth or breaks
in the skin. Once inside, they find a host cell to infect. For example, cold
and flu viruses will attack cells that line therespiratory or digestive
tracts.
A virus particle attaches to a host cell. The particle releases its genetic
instructions into the host cell. The injectedgenetic material recruits the
host cell's enzymes. The enzymes make parts for more new virus particles.
The new particles assemble the parts into new viruses. The new particles
break free fromthe host cell.

13. Virus :Living or Non Living?
Viruses are so primitive that many scientists consider themto be both living and
nonliving things. By itself, a virus is a lifeless particle that cannot reproduce. But
insidea living cell, a virus becomes an active organism that can multiply
hundreds of times. Before entering ones body it is inacive.
