No. They can only reproduce through taking control of a host cell.
The HIV is a virus and does not perform the bacterial reproduction of binary fission or conjugation in order to reproduce. The only way a virus reproduces is by infecting a host cell.
A virus needs a host cell to reproduce, so it enters a host cell(living cell e.g bacteria) and releases genatic materials which enslave the the cell and reproduce.
A virus does not need a crystal to reproduce, as they are not living organisms and do not have cellular machinery to perform reproduction. However, a virus does need a host cell to replicate and produce new virus particles.
There is no other living thing that requires a virus in order to reproduce.
Schizophrenia is not caused by a virus or bacteria--it does not and cannot "reproduce". Because it is not caused by a virus or bacteria, it is also not "contagious".
a Cell
Nothing reproduces inside a virus. It has to latch on the a host cell and insert its' DNA or RNA and then make the host cell reproduce virus particles.
No. The construction of a virus takes place inside of a host cell. The virus is 'not involved' in its own reproduction (in a manner of speaking). Viruses do not reproduce as cells do. A virus operates by injecting its genetic material and sometimes accompanying enzymes into a cell. It then essentially hijacks the cell and forces it to create more of the virus, usually killing the cell in the process.
All viruses do that. That's what makes a virus a virus.
A virus cannot reinvent itself without the help of a 'hosts' living cell. Once the virus invades the living cell it takes over the mechanism of reproduction using the cells enzymes and other chemical to reproduce. Therefore a virus cannot reproduce independently. Once the host cell is compromised the virus is free to infect other cells in the living organism.
Virus
I believe its the saliva glands.
