A virus mutates, and therefore it has which of the following traits of living things?(1 point) Responses
It grows and develops.
It is made of cells.
It evolves.
It uses energy.
It evolves.
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
They should get the flu vaccine because viruses mutate.
I apologize for the incorrect answers. Thank you for providing the correct responses. I appreciate your understanding.
Compare a virus to a unicellular organism.(1 point) Responses
Neither unicellular organisms nor viruses respond to stimuli.
Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.
Viruses need energy; unicellular organisms do not need energy.
Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.
Viruses reproduce through asexual reproduction; unicellular organisms need a host cell.
Summarize the lytic cycle.(1 point) Responses
A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.
A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
Differentiate between the lysogenic and lytic cycles.(1 point) Responses
The host cell copies its own DNA during the lytic cycle.
The virus injects DNA into the host cell during the lysogenic cycle.
Viral proteins are synthesized during the lysogenic cycle.
The host cell is destroyed during the lytic cycle.
The virus injects DNA into the host cell during the lysogenic cycle.
Why do doctors recommend people get the flu vaccine every year rather than every few years?(1 point) Responses
They should get the flu vaccine because their bodies do not build up resistance.
They should get the flu vaccine because viruses do not mutate.
They should get the flu vaccine because their bodies already have a resistance.
They should get the flu vaccine because viruses mutate.
