C) the skin's acidic pH and fatty acids
D) stomach hydrochloric acid
E) All of the choices are correct.

Accepted Answer

All of the choices listed are examples of nonspecific chemical defenses that help protect the body from pathogens. Lysozyme is an enzyme that breaks down bacterial cell walls; lactic acid and electrolytes in sweat, the skin's acidic pH and fatty acids, and stomach hydrochloric acid all create environments that are inhospitable to many microbes.
