Which one of the following statements about the structure of proteins is incorrect? select one: a. disulfide bonds provide strong intrachain interactions. b. hydrogen bonding stabilizes the a-helix proteins. c. nonpolar groups tend to face the outside of a protein in an aqueous solution. d. ionized amino acid side chains can form salt bridges within a protein. e. heat can disrupt tertiary structure.

Option (c).

Explanation:

Proteins are the main building block of the organism's body. The enzymes, clotting factors and antibodies are all made up of proteins. Proteins are the polymers of the amino acids.

Proteins consists of both the polar and non-polar groups. The nonpolar groups tend to face inside the protein in an aqueous solution so that proteins gets stable in this environment.

Thus, the correct answer is option (c).

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
