The correct response is:
**It evolves.**
Viruses can mutate, which is a form of evolution. However, they do not meet the criteria for being made of cells, using energy in the way living organisms do, or growing and developing in the traditional sense.

The correct response is:
**Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.**
Unicellular organisms are composed of cells with a plasma membrane, while viruses consist of a protein coat (capsid) and, in some cases, a lipid envelope but do not have a cellular structure like a membrane. The other statements are not accurate descriptors of the distinctions between viruses and unicellular organisms. For instance, viruses do not reproduce on their own and require a host cell to replicate, and both viruses and unicellular organisms do not respond to stimuli in the same way as multicellular organisms. Finally, both viruses and unicellular organisms do not require energy in the same way; unicellular organisms do require energy for their metabolism, whereas viruses do not utilize energy independently since they aren’t considered living organisms.

The correct response is:
**A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.**
This accurately describes the lytic cycle, in which a virus takes over the host cell's machinery to replicate itself and ultimately causes the host cell to lyse (burst), releasing new viral particles.

The correct response is:
**The host cell is destroyed during the lytic cycle.**
In the lytic cycle, the virus ultimately causes the host cell to burst, destroying it in the process. In contrast, during the lysogenic cycle, the viral DNA integrates into the host cell's DNA and can replicate along with the host cell's DNA without killing it immediately. The other statements do not accurately capture the key differences between the lytic and lysogenic cycles.

The correct response is:
**They should get the flu vaccine because viruses mutate.**
Flu viruses change frequently, and new strains can emerge each year. Annual vaccination helps ensure that individuals are protected against the most current strains of the virus.
