Scientists examined the folded structure of a purified protein resuspended in water and found that amino acids with nonpolar R groups were primarily buried in the middle of the protein, whereas amino acids with polar R groups were primarily on the surface of the protein. Which of the following best explains the location of the amino acids in the folded protein?

Polar R groups on the surface of the protein can form ionic bonds with the charged ends of the water molecules.

Polar R groups are too bulky to fit in the middle of the protein and are pushed toward the protein’s surface.

Nonpolar R groups that cannot form hydrogen bonds with water are pushed into the middle of the protein.

Nonpolar R groups from different parts of the protein form covalent bonds with each other to maintain the protein’s structure.

Which of the following best describes the condition expected after 24 hours? A dialysis-tubing bag filled with 3% starch and 3% glucose is placed in a beaker of distilled water.

The bag will contain more water than it did in the original condition.

The contents of the bag will have the same osmotic concentration as the surrounding solution.

Water potential in the bag will be greater than water potential in the surrounding solution.

Starch molecules will continue to pass through the bag.

A glucose test on the solution in the bag will be negative.
