Osmosis causes water to move from areas of low salt concentration to areas of high salt concentration. The internal NaCI concentration of red blood cells is 0.9 M. The diagram below shows red blood cells submerged in solutions of
four different NaCI concentrations-0 M, 0.65 M, 0.9 M, and 2 M.

Which of the diagrams shows red blood cells in the 2 M solution? Hi

what are the options?

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

it is called the mitotic spindle
