Which of the following is NOT a function of a hormone?

Correct Answer: D

Rationale: Hormones regulate internal environment (e.g., ADH for water), metabolism (e.g., thyroxine), glandular secretions (e.g., TSH), and growth (e.g., GH), but they don't produce electrolytes ions like sodium or potassium are managed by kidneys or diet, not synthesized by hormones. 'Produces electrolytes' is incorrect as hormones modulate existing substances, not create them. This distinction highlights hormones' role as signaling molecules, not producers of biochemical raw materials, critical for understanding endocrine specificity versus metabolic processes.

Correct Answer: C

Rationale: Aldosterone hyposecretion reduces sodium retention, lowering blood volume and pressure, leading to dehydration not heart rate, airway, oxygen, or pH changes directly. This distinguishes aldosterone's role in electrolyte balance, critical for hydration, contrasting with cardiovascular or acid-base regulators.
