The resting potential is generated by
A. K+ ions diffusing into the cell.
B. K+ ions diffusing out of the cell.
C. Na+ ions diffusing into the cell.
D. Na+ ions diffusing out of the cell.

B

Explanation:

Depolarization occurs by the opening of K+ voltage gated channels that cause K+ to leave the cell down a chemical gradient. This makes the inside of the cell less positive until there's reversal of polarity and eventually the resting potential is generated at -70 mV.

This is helped by ATP dependent Na+-K+ pumps.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
