No, i don't believe so.
I thought the equinoxes were when the Earth's axial tilt is greatest in relation to the sun, aka when the days are the longest/shortest.
Answer:A) No; action potentials result in increased permeability of the plasma membrane to sodium.
Explanation
Action potential is generated when influx of sodium ions occurs through the voltage gated ion channels in the nodes of ranvier cells, into the axoplasm. Provided the stimulus is strong enough more Sodium gated channels open and Sodium ions move in.
As sodium pump only pump sodium ions out of the cells , and it is sodium inlfux that causes action potentia,l this does not cause action potential .
In addition ATPs hydrolysis which supply energy for the sodium pump does not lead to action potential.
