Compare a virus to a unicellular organism. (1 point)
Viruses reproduce through asexual
reproduction; unicellular organisms need a
host cell.
Neither unicellular organisms nor viruses
respond to stimuli.
Unicellular organisms have a cell
membrane made from a lipid bilayer;
viruses have a protein coat.
Viruses need energy; unicellular
organisms do not need energy.
This comparison has some inaccuracies. Please find the corrected version below:
- Both viruses and unicellular organisms reproduce asexually, not just viruses. However, viruses require a host cell to reproduce; they cannot reproduce independently.
- Unicellular organisms can respond to stimuli, unlike viruses.
- It's true that unicellular organisms have a cell membrane made from a lipid bilayer, while viruses have a protein coat known as a capsid.
- The last point is incorrect. Both viruses and unicellular organisms need energy. However, viruses do not have their own metabolic systems and must rely on the host cell's energy. On the other hand, unicellular organisms can generate their own energy through various methods, such as photosynthesis or cellular respiration.
what is the answer
The accurate comparison would be: "Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat." This statement correctly differentiates between the physical structures of a virus and a unicellular organism.
Summarize the lytic cycle. (1 point)
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.
A virus injects its genetic material into the host
cell, copies itself, and then forms new viruses
that burst out of the host cell.
The lytic cycle is accurately summarized by the statement: "A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell."
Differentiate between the lysogenic and lytic cycles.
(1 point)
The virus injects DNA into the host cell
during the lysogenic cycle.
The host cell is destroyed during the lytic
cycle.
The host cell copies its own DNA during
the lytic cycle.
Viral proteins are synthesized during the
lysogenic cycle.
The differentiation between the lysogenic and lytic cycles is correctly described by the statements: "The virus injects DNA into the host cell during the lysogenic cycle. The host cell is destroyed during the lytic cycle." These statements characterize the key discrepancies between the two processes. However, it should be noted that this is a simplified description and these cycles involve more complex stages.
Why do doctors recommend people get the flu vaccine
every year rather than every few years? (1 point)
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
viruses mutate.
They should get the flu vaccine because
their bodies already have a resistance.
