7. Question 7
   Homeostasis is a fundamental process that enables organisms to maintain a stable internal environment despite external fluctuations. One of the essential components involved in homeostatic regulation is the endocrine system. Which of the following hormone pairs play opposing roles in regulating blood glucose levels, and how do they achieve this balance?
   • A.Insulin and glucagon; Insulin stimulates glucose uptake, while glucagon promotes glycogen breakdown.
   • B.Thyroxine and cortisol; Thyroxine increases blood glucose levels, while cortisol decreases blood glucose levels.
   • C.Estrogen and progesterone; Estrogen promotes glycogen breakdown, while progesterone stimulates glucose storage.
   • D.Epinephrine and norepinephrine; Epinephrine increases blood glucose levels, while norepinephrine decreases blood glucose levels.
