A student examines two skin samples under a microscope. Sample A is obtained from the palm of the hand, while Sample B is obtained from the forearm. The student observes that Sample A has a much thicker epidermis and numerous sweat glands but lacks hair follicles and sebaceous glands. Sample B contains hair follicles and sebaceous glands and has a thinner epidermis. Which statement BEST explains the difference between the two samples?
