question 20 (2.5 points)

Explanation:

Question 19

Simple goiter is often due to iodine deficiency. Potassium iodide provides iodine, which is used in early - stage treatment of simple goiter. Surgery is usually for more advanced cases or when other treatments fail. Antibiotics are for bacterial infections, not goiter.

The pituitary gland is called the "master gland" because it secretes hormones that regulate other endocrine glands (like thyroid, adrenal, etc.). The thyroid gland produces thyroid hormones, the adrenal gland produces stress - related hormones, and the pancreas is involved in blood sugar regulation.

Answer:

C. potassium iodide
