A) increases during childhood and adolescence.
B) increases during middle and late adulthood.
C) decreases during childhood and adolescence.
D) peaks in early adulthood.

Answer 1

A) increases during childhood and adolescence.

Step-by-step explanation:

Rapid eye movement sleep is a significant phase of sleep in which the movement of the eyes occurs randomly during the sleep. Such sleep increases the propensity to have a vivid dream. During childhood, the percentage of REM sleep during night increases. During adulthood, it remains constant while it starts to decrease in late adulthood.
