Explanation / Answer

9 ) False - Graded potential are formed in sensory neurons and are strong if the stimulus is strong . But these die out fast. The reason for this is because the membrane will always default to the resting membrane potential because ions are free to diffuse across the membrane. The way nerves get around this is by insulating themselves in myelin.
