Macronutrients (needed in relatively large amounts) are often listed as CHONPS. What does each of these letters indicate, and why are they needed by the cell

CHONPS stands for

C: carbon

H: hidrogen

O: oxygen

N: nitrogen

P: phosphorous

S: sulfur

They are needed by the cell because each of these elements combines to form the molecules that our body needs to exist since they make the biomolecules, which are amino acids, lipids, carbohydrates, nucleic acids, proteins, and vitamins.

Explanation:

CHONPS are the initials for the most abundant elements in our body (Carbon, hydrogen, nitrogen, phosphorous, and sulfur). CHOMPS form the biomolecules of our body. That is to say, they make lipids, carbohydrates, proteins, amino acids, and nucleic acids, so we need nutrients that contain the CHONPS elements, in large amounts, for our cells to function and the structure of our body.

as for the sky, according to nasa:

"sunlight reaches earth's atmosphere and is scattered in all directions by all the gases and particles in the air. blue light is scattered more than the other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time."
