Answer:
NaCl, because Na+is needed for glucose entry.
Explanation:
NaCl is the most beneficial for glucose absorption because of the action of the Sodium- Potassium ATPase, which is an enzyme that facilitates the adsorption of glucose into the cells.
It functions with the aid of energy by binding with the glucose or ATP and 3 ions of sodium. The ATP is hydrolyzed leading to the phosphorylation of the pump creating a conformational change of the pump. The ATP is deposited into the cells and Na+ released to the outside as K+ attach to the pump for dephosphorylation to take place. The cycle continues.

Answer: The original colour of grass is green because of photosynthesis. But in terms of reflection, it looks green because the sunlight reflects the green colour off the grass, so we see it as green.
Explanation: Sun appears white, but it is made up of the colors: red, orange, yellow, green, blue, indigo, and violet. When white light hits an object, it absorbs some colors and reflect the others. Grass appears green because it absorbs all the wavelengths except green. Green is reflected off the grass, so we see grass as green. The moon doesn’t have light of its own, the moon lights up because of the sun. So at night, as the light of the sun doesn't reach the grass directly because of the moon, it doesnt reflect any color off the grass, and so our eyes detect grass as black.
