timurjin [86]

Answer:

C

Explanation:

Because the newts with this mutation have faster reflexes, they are able to evade predators much better than the normal newts. This increases their chances of survival hence are more likely to reach reproductive age than the normal newts. Therefore they have a higher probability of passing their genes to the next generations. With each generation, newts with the mutated gene will increase.

What would the result be if a drug that blocks the action of rna polymerase was introduced into a virus-infected organism?
Svetllana [295]

Answer:

The correct answer is: viral replication would stop.

Explanation:

Drugs that block the action of RNA polymerase in viruses are called antivirals and are used to cure viral infections like Hepatitis and Herpes.

<u>Antivirals do not destroy the virus but rather mess with its development by inhibiting its replication</u>.

Viruses do not have the capacity to replicate or synthesize proteins by themselves, so they need a host that can "lend them" the structures needed to perform those processes. If the drug blocks the RNA polymerase, the virus won't be able to replicate itself.
