Explanation / Answer

1. (A) Alpha Cells is the Islets of Langerhans secrete the hormone Glucagon which increases the level of Glucose in the blood.

2. TRUE. Thyroid Hormone increases the metabolic rate of the body and thereby increases the heat which raises the temperature of the body. If the secretion of thyroid hormone decreases then less heat is produced and the body temperature decreases.

3. FALSE. A deficiency of insulin receptors would increase the level of blood sugar.

4. TRUE. Regardless of the cause of stress, the body reacts in a fairly consistent way to different stressors. The body undergoes changes that are fairly consistent for different stressors.
