Can viruses live on their own?
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).
The cell infected by a virus is referred to as the?
The cell infected by a virus is referred to as the host cell. The virus hijacks the host cell's machinery to replicate and produce more virus particles.
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.
Why is the cell invaded by the virus called a host cell?
The cell invaded by the virus is called a host cell because it provides the environment and resources necessary for the virus to replicate and multiply. The virus uses the host cell's machinery to produce more viruses, ultimately leading to the destruction of the host cell.
What do you call a cell that has been infected with a virus?
It is called a host cell. The virus attaches to the cell and injects its DNA into the cell. The virus's DNA overruns the "instructions" that the cell has and "tells" the cell to make copies of the virus using the DNA. Then the cell makes so many copies of the virus, that it explodes. The new viruses then go on to attach to other cells.
What is a virus called outside a host 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.
What is outside a living cell virus?
faeces
What is a dormant virus?
Any virus that is not modifying a cells behavior is considered dormant; it may be in a cell but not active, or outside a cell (where it can't be active).
Can the HIV virus live outside the human body in fluids if not smeared?
Yes, infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate or breast milk.
Does a virus get energy by reacting chemicals with oxygen?
No, a virus has no metabolism whatsoever. It relies entirely on tricking the host cell to do its work; while outside a cell, the virus doesn't move, eat, or anything.
Why do biologist hypothesize that cell evolved before virus?
A virus is a parasite, that can only live on cells.
How long does a virus live in a hostile environment outside the host?
Depending on the virus, it can live for several minutes up to a week or more depending on the environmental conditions.
What do you call that a virus invades?
A virus which invades a cell can be said to be virulent. One that causes the host cell to immediately produce virus' particles and lose it's ability to live is said to be a lytic virus. A virus that remains "silent" for awhile is called a lysogenic virus.
What are minute parasitic microbes that live inside another cell?
virus
Are clothes of herpes zoster contagious?
The virus has a limited time it can live outside of the body. It is not likely to contract the virus from clothes.
Can aids virus survive under outside temperature?
No. HIV needs a host. It does not live long, outside the body.
How long a hepatitis virus can stay outside the host?
Hep B can live for up to a week outside the body.
