Depending on the environment, anywhere from minutes to about 14 hours.
No
No, because for a virus to reproduce, it needs a cell to take energy and stuff from. When the cell is dead it moves on to another cell. It short, it is very hard for a virus to reproduce or multiply, without a host (e.g. a red blood cell).
A host organism is one that provides a source of energy or a suitable environment for a virus or another organism to live and thrive. The host may not always benefit from this relationship and can sometimes suffer harm from the presence of the virus or other organism.
They cannot live outside of a host.
Yes virus cannot survive on the atmosphere beside living in host. It is a kind a neutral parasite which acts like a non living but works on the living cell
A virus outside a host cell is generally referred to as a virion. This is the inactive form of the virus that is unable to replicate until it enters a suitable host cell.
No. HIV needs a host. It does not live long, outside the body.
Hep B can live for up to a week outside the body.

No
Yes, infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate or breast milk.

It depends on the kind of Bacteria you are talking about. Most do not depend on a host and live on their own. Some, such as E. coli can live outside a host at least for some time. A few are entirely dependent on a host.
parsites are of two types- ectoparasites and endoparasites............... endoparasites are those parasites which live inside the body of its host. ectoparasites are those parasites which live outside the body of the host. endoparasites take up the food that the host eats as they live inside the body of the host. eg- worms inside the stomach take up the digested food from the stomach. ectoparasites, as they live outside the body of the host take up the nutrition from outside the body of the host. eg- mosquitoes suck blood from our body.
Indeed, ectoparrasites manifest on the outside of the bode of the host, ecto means outside. Examples are fleas and thicks. Endoparasites are the opposites and live inside the body, endo means inside.
Tapeworms can live in a host for 5-10 years.
