Chemically hormones are:
Correct answer: D. Both B and C
- A. Carbohydrates
- B. Proteins
- C. Steroids
- D. Both B and C
Explanation
Option D is correct. Chemically, hormones are classified into two main types: Protein hormones. Protein hormones are made up of amino acids and are the most common type of hormone. These hormones are produced by the endocrine glands, such as the thyroid gland, the pituitary gland, and the adrenal glands. Steroid hormones: Steroid hormones are made up of cholesterol and are produced by the adrenal glands and the gonads (ovaries and testes).

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
