The Na+/K+ pump generates a membrane potential across the plasma membrane (PM) of the cell by transporting Na+ and K+ across the PM. The action of this pump results in the cell having a slightly charge inside the cell compared to the extracellular space.

Explanation:

The sodium-potassium pump transports sodium out of  the cell and potassium into the cell through plasma membrane. In each cycle, 3 sodium ions exit the cell, while 2 potassium ions enter. For every three ions of sodium that move out of the cell, only two ions of potassium move inside the cell, resulting in a more negative charge inside the cell interior. This generates membrane potential.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
