What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
What type of virus enters the cell and doesn't immediately attack?
Hidden viruses, I believe.
How do viruses kill cancer cells?
Because they attack the cells in the body and cancer cells are just the mutated cell of our body very good question by the way
Why it is difficult to isolate drugs effective against eukaryotic microorganisms and viruses?
To find defenses against a eukaryotic microorganism is difficult because we are eukaryotic organisms and any attack on the cell of the microorganism can be an attack against our own cells. This requires a subtle approach. Viruses have no metabolism, are not really living and do not reproduce without a host. So, they leave little open to attack in their simplicity.
What are serotypes?
A serotype is a group of microorganisms, cells, or viruses, categorized together based on their cell surface antigens.
Why antibiotics don't work on viruses?
Antibiotics do not work on viruses because viruses are not alive. A bacterium is a living, reproducing lifeform. A virus is just a piece of DNA (or RNA). A virus injects its DNA into a living cell and has that cell reproduce more of the viral DNA. With a virus there is nothing to "kill," so antibiotics don't work on it.

Why viruses are refered to as obligate parasites?
Because viruses can not reproduce or produce protein without a host cell
What happens to the viruses after they lyse the cell wall?
The bacteriophage enzyme lyses the bacteriums cell wall, which then releases a new bacteriophage particle that can attack other cells
Viruses are considered an exception to the cell theory because they normally reproduce?
only in a host cell
Which virus enters a cell and the virus's genetic material becomes part of the cell?
This is something all viruses do in effect when they attack a cell and make the cell start producing new viruses as a part of their reproductive process. See the related question below about the Lytic Cycle which describes the steps in that process.
Why would viruses not grow on milk?
Viruses do not grow because they are not alive. They can reproduce, but only inside a host cell.
Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
