Question

Quizplus · Accepted Answer

Graded potentials can act as signals over short distances and can either cause or prevent an action potential depending on the strength and timing of the signal. However, they cannot propagate over long distances without decrement, unlike action potentials that can travel long distances without loss of signal strength.
