How does a virus affect humans?
A virus affects humans by invading a cell. The virus then forces the cell to produce viral material rather than cell material. This causes the cell to replicate the virus rather than itself.
Why is a host cell unable to make its own proteins if the invading virus replicates?
The reason why a host cell is unable to make it`s protein while the invading virus replicates is because viruses typically not considered living organisms
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.
Why is there no virus kingdom?
A virus isn't alive it cannot reproduce without invading a 'host cell' therefore it does not fit the criteria of a life form and cannot belong to a biological kingdom.
An invading foreign material such as that on a virus is an?
antigen
1What is the role of macrophages in the general response to infection?
It surrounds the virus. Once the invading cell is inside the phagocyte it is killed by enzymes.
Where can I get a Drawing of a virus cell?
No where. A virus is not a cell.
What does a cell and virus have in common?
What a cell and a virus have in common is the RNA or DNA. The virus can be either a RNA virus or a DNA virus.
What three steps occur after a virus attaches and enters a host cell?
When a virus enters a cell and is active, it causes the host cell to make new viruses, this process destroys active virus functions inside a cell.....it like 'tricks' the host cell that it's one of the cells
The virus that causes AIDS is damaging to the body because it?
targets cells that fight invading microbes
Which is smaller a cell or virus?
A virus.
Which component of a virus is lacking in a cell?
Both a living cell and a virus contain nucleic acid. The virus has a capsid, whereas a living cell does not.
