Compare a virus to a unicellular organism.(1 point) Responses Viruses need energy; unicellular organisms do not need energy. Viruses need energy; unicellular organisms do not need energy. Neither unicellular organisms nor viruses respond to stimuli. Neither unicellular organisms nor viruses respond to stimuli. Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat. 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 The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself. 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 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. 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 correct response is: **It evolves.**

While viruses exhibit some characteristics associated with living things, such as mutation and evolution, they do not meet all the criteria for being classified as living organisms, such as being made of cells, growing and developing in the traditional sense, or using energy independently.

The correct response is: **Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.**

This statement accurately describes the structural differences between unicellular organisms (which are living cells) and viruses (which are not classified as living organisms in the traditional sense). Unicellular organisms have a lipid bilayer cell membrane, while viruses are composed of genetic material surrounded by a protein coat (capsid).

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 statement accurately describes the lytic cycle, which is a process wherein a virus enters a host cell, replicates its genetic material, assembles new virus particles, and eventually causes the host cell to lyse (burst), releasing the newly formed viruses to infect other cells.
Answered by GPT-4o mini
The correct response is: **The host cell is destroyed during the lytic cycle.**

In the lytic cycle, the virus causes the host cell to burst, leading to the destruction of the host cell. In contrast, during the lysogenic cycle, the viral DNA integrates into the host cell's genome and can replicate along with it without immediately destroying the host cell. This distinction is key in differentiating between the two cycles. The other statements provided are not accurate descriptions of the processes involved in either cycle.

The correct response is: **They should get the flu vaccine because viruses mutate.**

Flu viruses mutate frequently, which can result in new strains that the immune system may not recognize. As a result, the vaccine is updated each year to provide protection against the most current strains circulating in the population. Getting vaccinated annually helps ensure that individuals have the best possible immunity against these evolving pathogens.
