The refractory period makes the cell rest. In this period, the cell becomes able to depolarize again by collecting ions.
A burning splint will burn more vigorously in pure oxygen than in air because <span>oxygen is a reactant in combustion and concentration of oxygen is higher in pure oxygen than is in air.
Oxygen concentration in air is approximately 20%, the rest of are nitrogen, carbon dioxide and other gases. Oxygen is oxidazing reactant, that means oxygen give electrons in chemical reactions.

The correct answer is less wind and more wind. Good luck :)
