The following are the main steps in the generation of an action potential: 1. sodium channels are closed 2. more voltage-regulated potassium channels open and potassium moves out of the cell, initiating repolarization 3. sodium channels return to their resting properties 4. a graded depolarization brings depolarization to threshold 5. a temporary hyperpolarization occurs 6. sodium channels open 7. sodium ions enter the cell and further depolarization occurs The proper sequence of these events is

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. calcium carbonate is strengthened by phosphorus.

explanation:

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
