Based on the scenario below, select the statement that accurately finishes the sentence.
Furkat [3]

Answer:

A. damaged her peripheral nervous system because the information regarding taste cannot be transmitted back to her brain.

Explanation:

The nervous system is an important system of our body and is directly related to our survival. This system is linked to the coordination of the organism's various activities and is also responsible for allowing the interpretation of the environment around us.

The nervous system is an important system of our body and allows us to have emotions, to remember an important moment in our lives, to interpret smells, tastes and images, to make movements and even to stay alive through the automatic breathing and heartbeat.

Taste, that is, the sense of taste is directly linked to the peripheral nervous system. For this reason, if Stacey has lost her sense of taste, we can conclude that she has damaged her peripheral nervous system because taste information cannot be transmitted back to her brain.

Differentiate between persistent and latent animal virus infections.
lana66690 [7]

Answer:

The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.

On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.

Explanation:

In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.
