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?
When a virus infects a host cell, it hijacks the cell's machinery to replicate its own genetic material and proteins instead of the host cell's. This often leads to disruption of the host cell's normal protein synthesis processes, which can prevent the cell from making its own proteins.
How can a virus destroy cells?
A virus can destroy cells by invading them, using the cellular machinery to replicate, and eventually causing cell death. This process can disrupt normal cell function and lead to tissue damage and inflammation.
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 advantage does a virus have when invading an organism if it incorporates part of a host cell membrane into its envelope?
By incorporating part of a host cell membrane into its envelope, a virus can disguise itself and evade detection by the host's immune system. This camouflage allows the virus to enter host cells more easily without triggering an immune response, increasing its chances of successful infection.
Do virus replicate?
Yes, viruses replicate by invading host cells and using their cellular machinery to produce copies of themselves. This replication process can lead to the spread of the virus to other cells or individuals.
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.
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 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
