The correct answer is option C, that is, from negative to positive.  

Action potentials are those electrical impulses, which transmit signals around the body and are nothing more than a temporary shift, that is, from negative to positive in the neuron's membrane potential resulting due to the flowing of ions in and out of the neuron suddenly.  

During the resting state, that is, prior to an action potential, all of the gated potassium and sodium channels are closed. They open once an action potential has been initiated. The sodium channel opens and more sodium ions move within the cell, making the charge more positive.

vfiekz [6]

The kidneys are a pair of bean-shaped organs on each side of your spine<span>, under your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. It goes to the kidneys to extract water from the excretory system and put it back into the blood. Kidneys filter your blood. They eliminate wastes, control the body's fluid balance, and hang onto the right levels of electrolytes. All of the blood in your body passes through them quite a few times a day.</span>
