Final answer:
Having myelin does indeed increase the velocity of conduction.
Step-by-step explanation:
The statement that having myelin increases the velocity of conduction is true.
Myelin is a fatty substance that wraps around axons, which are the long extensions of nerve cells. It acts as an insulating layer, which helps to speed up the transmission of electrical signals, known as action potentials, along the axon.
By providing insulation, myelin prevents the loss of electrical charge, allowing the action potential to travel more efficiently and quickly. This is why having myelin increases the velocity of conduction.
