Confusing question. Essentially, one way your body recognizes viruses by the antibodies it left behind the last time you were infected. Another is the sheer presence of something "different."
Antibodies (immunoglobulin) are Y-shaped proteins that are produced by plasma cells, and which have millions of variable. At each tip of the "Y" is an antigen binding site (paratope), in essence a lock. When your body comes into contact with a foreign pathogen or substance, the antibodies (epitopes) of the invader trigger the immune system to produce antibodies. the antibodies with paratopes that correspond to the epitopes of the invader are attached, and the invader is neutralized or killed.
The problem occurs when your body does notrecognize a virus or some other invader. At these times your body has no or reduced defense against the pathogen, and in serious cases (bubonic and pneumonic plagues, dengue and hemorrhagic fevers, ebola, haunta, super flues such as H1N1 or Swine Flu, and SARS) the immune system cannot fight it and becomes overrun.
Any invasion of the body by a foreign substance or pathogen automatically triggers an immune response. In very simple terms, the body produces what are called cytokines. Cytokine are cell-signalling proteins, peptides, and glycoproteins and are molecules that message the presence of any substance or pathogen they see as an invader. Cytokines are one of the first steps in the innate immune system, and can trigger the production of other cells, biochemicals, hormones, and other immunological responses that attack and work to remove the threat. How they mark and target invaders and initiate production of the various types of immunological response is still not very well known.

What advantage does a virus have when invading an organism if it incorporates part of a host cell membrane into its envelope?
Envelopes aid the virus in entering the host's cells. Glycoproteins on the envelope's surface are unique to the virus. They identify and bind to receptor sites on the host's cell membrane.
Cell in which a virus multiplies it self?
A virus replicates inside a host cell. For example 'Bacteriophase'
What is a virus called outside a host cell?
virus can't live outside host cell
Does the host cell usually benefit from having a virus?
The host cell does not benefit from having a virus. The virus usually kills it.
What does a virus do to its host cell?
virus want to the enzymes of their host cell for grow and reproduction so it take many enzymes which want o the host cell.

What is the cell that a virus infects?
Host Cell
How do you describe an active virus?
The virus attaches to the host cell, it takes over the functions of the host cell, and it eventually destroys it. If there was no host cell, the virus would die.
Cell in which a virus multiplies it self?
A virus replicates inside a host cell. For example 'Bacteriophase'
What stage is it when a virus enters a host cell?
The virus enters the host cell in the penetration phase.
What is a virus called outside a host cell?
virus can't live outside host cell
Does the host cell usually benefit from having a virus?
The host cell does not benefit from having a virus. The virus usually kills it.
What can a virus do without a host cell?
It can do nothing. It needs the host cell to make more virus particles.
What is a process that a virus can do in a host?
First the virus enters the host cell, then the virus' hereditary material come, then the host cells hereditary material becomes viral, then the host cell expands, and then it POPS!!!
Where does a virus multiplied?
Viruses can only multiply (reproduce) within a host cell. The type of host cell is dependent on the virus' host range.
The cell a virus lives on or in is called?
A virus will replicate within a host cell.
What is the cell in which a virus reproduces?
This is called a host cell. In the beginning, a virus will attach itself to the host cell and release its genetic material into it. This genetic material interferes with the host cell's enzymes which cause them to form parts in which will create a new virus.
