B. improve the accuracy of nerve impulses
C. increase the strength of nerve impulses
D. communicate with other cells

Answer 1

A

Step-by-step explanation:

Answer 2

A. increase the speed of nerve impulses

Step-by-step explanation:

Schwann cells speed up nerve impulses by secreting a fatty substance called myelin around the axon of peripheral nerves. (Myelin can greatly increase the speed of impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.)
