Explanation:

1. Adrenaline effects include increased heart - rate, blood pressure, and energy release. It prepares the body for a 'fight - or - flight' response.
2. Adrenaline gets you ready for the fight - or - flight response.
3. Adrenaline is secreted in high - stress or dangerous situations like being chased by a wild animal.
4. Melatonin production is highest at night when it's dark.
5. Melatonin is secreted by the pineal gland.
6. Melatonin levels do not remain constant during the night; they rise in the evening and fall towards morning.
7. Insulin affects liver cells, muscle cells, fat cells, and some cells in the pancreas.
8. Insulin causes cells to take up sugar and causes blood sugar to decrease.
9. Glucagon causes the liver to release stored sugar.
10. Glucagon causes blood sugar to increase.
11. The pancreas secretes insulin and glucagon.
12. When you exercise, blood sugar levels drop, causing the release of glucagon to bring those levels back to normal ranges.
13. Matching:

• Raises blood sugar: B. glucagon
• Helps you sleep: D. melatonin
• Increases muscle strength: A. adrenaline
• Lowers blood sugar: C. insulin

Answer:

1. Increased heart - rate, increased blood pressure, energy release.

3. High - stress or dangerous situations (e.g., being chased by a wild animal)
4. At night when it's dark
5. Pineal
6. No
7. Liver cells, muscle cells, fat cells, pancreatic cells
8. Take up; decrease
9. Liver
10. Increase

12. Drop; glucagon
13. 1. B. glucagon
14. D. melatonin
15. A. adrenaline
16. C. insulin
