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

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.

the answer to your question is:

c. complementary base-pairing

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
