Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.

Answer: The rays of the summer sun, high in the sky, arrive at a steep angle and heat the land much more than those of the winter sun, which hit at a shallow angle. Although the length of the day is an important factor in explaining why summers are hot and winter cold, the angle of sunlight is probably more important.
