Question

the thyroid gland ______

• increases the energy of the body
• produces bile
• controls the actions of all other endocrine glands
• aids digestion

Explanation:

• Analyze each option:
• "Increases the energy of the body": The thyroid gland produces hormones (like thyroxine) that regulate metabolism, which affects the body's energy levels. This is correct.
• "Produces bile": Bile is produced by the liver, not the thyroid. Eliminate this.
• "Controls the actions of all other endocrine glands": The pituitary gland is the master gland that controls other endocrine glands, not the thyroid. Eliminate this.
• "Aids digestion": The thyroid's main role is metabolic regulation, not direct digestion aid. Digestive aids are from organs like the stomach, pancreas, etc. Eliminate this.

Answer:

A. increases the energy of the body
