Question

1.A virus mutates, and therefore it has which of the following traits of living things?(1 point)

It uses energy

It evolves.

It grows and develops.

It is made of cells.

2.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.

3.Summarize the lytic cycle.(1 point)

A virus copies its genetic material and then splits its cell membranes in half to form identical viruses.

A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.

The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.

A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.


4.Differentiate between the lysogenic and lytic cycles.(1 point)

The host cell copies its own DNA during the lytic cycle.

The host cell is destroyed during the lytic cycle.

The virus injects DNA into the host cell during the lysogenic cycle.

Viral proteins are synthesized during the lysogenic cycle.

5.Infer why doctors recommend people, especially elderly and those with weak immune systems, get the flu vaccine every year.(1 point)

They should get the flu vaccine because viruses mutate.

They should get the flu vaccine because their bodies already have a resistance.

They should get the flu vaccine because viruses do not mutate.

They should get the flu vaccine because their bodies do not build up resistance.


Please i really need help

Answer 1

Answer:

1. It grows and develops

2.  Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

3. A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

4. The host cell is destroyed during the lytic cycle.

5. They should get the flu vaccine because their bodies do not build up resistance.

Explanation:

These are the answers I chose from when i did it  10 minutes ago, they wont let me go back to the quick check to confirm it, but this was the best I could do.

Answer 2

The trait of living things that's depicted by a virus that mutates is that it evolves.

The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

The lytic cycle is when 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 difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.

The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.

It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.

People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.

Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.

In conclusion, the correct options are B, C, D, B, and A.
