Virus require a host to carry out the most of the characteristics of living organisms. In almost cases, viruses require a host to reproduce (by hijacking the cells of the host and using its DNA to make copies of itself) and also receive the bulk of their energy from the host.

What is the relationship that exist between a virus and a human when the virus infects the human?
pathogen/host
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 is the differences between a virus a host and a parasite?
A virus is a small infectious agent that can only replicate inside the living cells of an organism. A host is an organism that provides nourishment and a habitat for another organism. A parasite is an organism that lives on or inside another organism (the host) and benefits at the host's expense.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
Can a virus grow and replicate within a host organism?
Yes, a virus can grow and replicate within a host organism by hijacking the host's cellular machinery to produce more virus particles.
