not that i know of.
but im only a physics student :)
a virus has no metabolism.a virus cannot reproduce independently, it must infect a cell.a virus is much smaller than a cell.
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.
This describes a virus. Viruses are unique microorganisms that cannot reproduce on their own; they require a host cell to replicate. Once inside a host cell, they hijack the cell's machinery to produce new virus particles. This dependence on host cells distinguishes viruses from other types of organisms, such as bacteria, which can reproduce independently.
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.
they reproduce independentlyThis is a false statement as viruses need a host cell and it's replicative machinery to reproduce their genetic material.
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
A plasmid.
No, a bacterium is a complete, albeit single-celled organism; as such it can locomote, reproduce, and perform the other functions common to independently living things. A virus, OTOH, is a strand of DNA incapable of reproducing on its own (to do that, it's got to invade/infect a host 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.
Reproduce (they make copies rather than reproducing), create waste, and (need energy? i.e. consuming foods)....wait, can you specify what virus you're talking about?
