E) both (a) and (c).

Question

Quizplus · Accepted Answer

Graded potentials are local changes in membrane potential that occur in varying degrees of magnitude and serve as short-distance signals. They do not travel long distances like action potentials, so option (c) is incorrect. Therefore, the best choice is (a) and (b) which corresponds to option D.
