Answer:
A. increase the speed of nerve impulses
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.)
I hope this helps! :)
The energy that's required to break bonds is called bond energy. Bond energy is used in chemistry, represented by an E, and accounts for measuring the strength of a bond in a chemical bond.
