Question

Quizplus · Accepted Answer

Cortisol is a hormone that is typically released in larger amounts during the morning hours, which can help to promote wakefulness. Therefore, it is likely that the researchers would find higher levels of cortisol in Bradley's body just before he wakes up during the study. Melatonin is a hormone that is typically released in the evening and at night to promote sleep, so it would not be present in large doses just before waking up. Growth hormone and prolactin are hormones that are also typically released during sleep, but they would not necessarily be found in large amounts just before waking up.
