b. too much exercise

d. lack of sleep affecting mood regulation

Explanation:

First Question:

Melatonin is a hormone that regulates sleep - wake cycles. Teens often have a delayed production of melatonin, which makes them feel wide awake at midnight. Overeating, excessive hydration, and lack of exercise are not the main reasons for this sleep - wake pattern disruption related to the body's internal clock.

Lack of sleep can affect the body's mood regulation systems. Ghrelin is related to hunger, too much exercise is not related to gaming late at night, and excess hydration is not a typical cause of feeling overwhelmed or irritable after gaming late. So the lack of sleep from gaming late affects mood regulation.

Answer:

a. Delayed melatonin production
