If sarah had a viral infection that affected neuron function in the ventral root of the same spinal nerve, how would the signs and symptoms be different than those she has now

The symptoms that are caused by affected ventral roots are the following:

Sarah will not feel pain but her ability to locomotion will be affected.

Explanation:

The question here is Why Sarah will not feel pain ?

the answer is that neurons help us in sensation of pain, burn and touch. If the major part of spinal nerve is damaged how she will feel sensation of pain.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
