B. initiate an action potential.
Action potentials are initiated when a depolarization reaches a threshold potential. This threshold potential varies, but is normally around 55 or 50 millivolts above the resting potential of the cell, which implies that the input current of sodium ions exceeds the output current of potassium ions.
Just do energy spent divided by time to get your answer. With this we can say a human might be able to!
A
The scientific study of weather is called meteorology.
