Detailed explanation-1: -Q. Which best explains how a nonliving virus is able to reproduce? A virus becomes living when in contact with a host organism.
Detailed explanation-2: -Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Detailed explanation-3: -A virus infects a host organism by pulling the DNA from the cells of the host organism into itself.
Detailed explanation-4: -The virus’s genome is uncoated from the protein and injected into the host cell. Then the viral genome hijacks the host cell’s machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids. Next, the viral particles are assembled into new viruses.
Detailed explanation-5: -Once a virus gets into a host’s body, it travels along the surfaces of cells until its proteins begin to bind with receptors on the cells. The virus and the cells then fuse, allowing the DNA or RNA inside the virus to enter the cells, where it begins to reproduce.
