the immune system attacks and destroys cells of the pancreas, where insulin is made
the pancreas makes more insulin.
lead to increase of insulin producing beta cells
the cells dont respond to insulin like they should

Explanation:

• Question 3: Cortisol is a hormone produced by the adrenal glands. It plays a role in mobilizing energy stores (such as breaking down glycogen to glucose) during stress - related situations. Aldosterone is mainly involved in electrolyte balance. ACTH (Adrenocorticotropic hormone) is produced by the pituitary gland and stimulates the adrenal glands. Epinephrine is also from the adrenal glands but is more associated with the "fight - or - flight" response in a more immediate sense rather than long - term energy mobilization.
• Question 4: Melatonin production is sensitive to light. Light exposure (especially blue light) can suppress melatonin production. Turning on lights in the middle of the sleep cycle would lower melatonin. Sound, getting out of bed, or opening eyes (in a dark environment) do not have the same direct impact on melatonin levels as light.
• Question 5: In type 2 diabetes, the cells become resistant to insulin, meaning they don't respond to insulin like they should. In type 1 diabetes, the immune system attacks and destroys pancreatic cells. In type 2 diabetes, initially, the pancreas may produce more insulin to compensate for the resistance, but this is not what "goes wrong" in terms of the fundamental defect. There is no increase in insulin - producing beta cells in type 2 diabetes.

Answer:

• Question 3: Cortisol
• Question 4: turning on the lights
• Question 5: the cells don't respond to insulin like they should
