They are obligate in the sense that they cannot replicate outside of a host cell.
To make a copy of itself, a virus must first enter a cell (intracellular), hijack the machinations of said cell (parasitic behavior) and then copy itself.
Virus becomes parasite and plays its role after it gets inside a living thing ,there life is like made to get inside the livingthing and play it's role therfore their getting of parasite only after getting inside a living thing is said as an obligation for them to be a parasite when they are not inside livingthing i.e,there main life phase in which they are out of the livingthing where nature gives virus a beggining form which is out of living thing hence, it sustains in obligation to be a parasite so,virus are obligatory parasite.
Because they absolutely require living host cells in order to multiply
Organisms who use another organism to flourish are called parasites.
Yes. Rabies is a virus and could be called a parasite.
Virus and bacteria do not have.Other eukaryotic paracites have
Neither; influenza ("the flu") is caused by a virus; in particular, an RNA virus of the family Orthomyxoviridae, of which there are several varieties. The flu virus could be thought of as parasitic, since it does invade host cells and use these cells for its replication. But though some biologists may consider bacteria and viruses to be parasites, the medical field does not.
Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).
yes.
Organisms who use another organism to flourish are called parasites.
No Lymphatic Filaraisis is not a virus. It is caused by three different types of parasites called Wuchereria bancrofti, Brugia malayi, and Brugi Timori
Yes. Rabies is a virus and could be called a parasite.

A parasite is any organism that lives on or in another organism, not necessarily a fungus, virus or bacteria.
the only thing viruses have in common with them is that they move
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
An Interferon virus is released by host cells as a response to pathogens which includes viruses and parasites. When something becomes infected then an Interferon is sent out as a warning of the virus to stop the transcription.
They are usually just called organisms or bacteria, virus, pathogen, or parasites.
