One student designed an experiment with sugar, water, and sand. The steps of the experiment are shown below.

• Make a thumb size hole at the bottom of an 18 oz styrofoam cup.

• Roll a piece of paper into a tube and place it in the middle of the cup over the

hole.

• Fill the tube with sugar and surround the tube with sand.

• Pull out the paper tube slowly from the cup and then dip the cup into a beaker

of water.

• Watch the sugar cubes dissolve in water to form gaps in the sugar layer.

The student's experiment demonstrates the formation of

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.
