a. Aldosterone
b. Cortisol
c. Anti-diuretic hormone
d. Oxytocin
e. Melatonin

Answer 1

Answer: e. Melatonin

Step-by-step explanation:

Seasonal affective disorder is a kind of depression that develops due to change in seasons. It begins and ends at the same time every year. Specifically, it starts in the fall and remains to continue in the winter months. The person experiences a lack of energy, insomnia, or prolonged sleeping and feels moody.

The change in season will disrupt the balance of the level of secretion of melatonin, which plays an important role in sleep patterns and mood. It regulates the sleep and wake cycle. In winter months due to lack of exposure to sunlight the melatonin secretion decreases.
