Which statement is true regarding axons and dendrites?a) Action potentials travel along the axon. b) The dendrite terminal is the site where neurotransmitters are released into the synaptic cleft. c) Neurons generally possess more axons than dendrites. d) In a neuron, axons typically receive signals, and dendrites typically transmit or send signals.

Action potentials travel along the axon.

Explanation:

Action potential produces in four steps:

(1) Depolarization to the threshold.

(2) Activation of the Na+ channel and rapid depolarization.

(3) Inactivation of Na+ channel and activation of the K+ channel.

(4) Return to normal permeability.

The action potential travels by an unmyelinated axon. Their only 1 segment of the axon affects by the action potential. Then a local current helps to depolarize another segment to the threshold and again cycle repeats.

Another is an action potential travel by a myelinated axon. In this, the current is generated by the action potential and jumps from the node of Ranvier to the next segment.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.
