Answer: Decreased levels of melatonin
Explanation: Melatonin is a substance that is excreted at night and by which the brain sends signals that one should sleep, that is, a man / woman is feeling sleepy. When melatonin secretion decreases, the alertness increases, as is the case with Colby. Melatonin levels decrease at the base of the brain signal regardless of whether or not Colby slept enough the previous night. Feeling tired will induce some other receptors and consequent signals from the brain, but a natural decrease in melatonin throughout the day occurs normally.
In the supply curve and the demand curve, the equilibrium is reflected where the two curves intersect.
<u>Explanation:</u>
Equilibrium is fundamentally the condition in which the factors involved in the operation achieve balance of values with respect to each other. In the discipline of market economics, two major factors involved are that of supply and demand.
The equilibrium between supply and demand is achieved when the demand for a commodity or a service in the market is equal to the supply of the respective commodity or service.
When represented graphically, the condition of equilibrium is depicted through the intersection of the demand and supply curves.
