Explanation:

Question 13

Thyroid hormones (like T3 and T4) are synthesized using iodine. Zinc, iron, and potassium have other roles in the body but are not part of thyroid hormone structure.

Thyroxine (a thyroid hormone) increases metabolic rate, which generates heat and helps maintain body temperature. Glucagon regulates blood sugar, somatotropin (growth hormone) has growth - related roles, and parathyroid hormone regulates calcium.
