Answer:

The two prokaryotic domains are Archaea and Bacteria.

The eukaryotic domain is Eukarya.

Both prokaryotic and eukaryotic are similar in which they have a plasma membrane and cytoplasm; meaning all cells have plasma membrane surrounding them. A difference between Eukaryotic and Prokaryotic is that eukaryotic have organelles, for example, a nucleus. Prokaryotic cells do not have a nucleus.

How does the virus use a host cell to make copies of itself
vagabundo [1.1K]

Answer:

I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.

If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).

In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.

In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

Explain how an organism's ability to survive and reproduce can affect the entire population
inn [45]

Answer:

The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.

Explanation:

According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>
