Answer to Question 1

C
A sleep cycle is usually 70 to 90 minutes in duration, and the typical sleep passes through four to six cycles during a 7- to 8-hour sleep period. The NREM and REM periods of sleep change as the overall sleep period continues and the person becomes more relaxed and reenergized. About 75 of sleep is NREM sleep.

Answer to Question 2

A
In stage 1 sleep, which usually lasts about 10 minutes, electroencephalogra m (EEG) frequency slows, eyes roll slowly from side to side, and muscle tension is reduced; because this is a light stage of sleep, the person can be awakened easily.
