Multiple sclerosis is a demyelinating disease of the central nervous system caused by antibodies that invade the central nervous system and bind to the myelinating cells. this has an affect on the signal propagation. you would expect to find antibodies on:
a. microglia
b. neurons
c. schwann cells
d. astrocytes
e. oligodendrocytes

The answer is C: Schann cells

Explanation:

We will find the antibodies of multiple sclerosis at the level of schawnn cells, which are the support cells of the neurons that are going to involve the axons. This disorder will lead to an alteration in the nerve conduction, producing an alteration of the electrical conduction of the axons.

To conduct a scientific investigation without bias, you would need to select a random sampling of people and set up preliminary guidelines. Questions need to be conducted and answers collected in the same manner for all people interviewed.
