the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.

answer:

Power braking's benefits

Among the big advantages of a power braking system are it's: Regarded as safer. The heat caused by the friction of drum brakes causes them to wear down. Because disc brake systems have better heat distribution, they're more efficient
