Answer to Question 1

ANS: B
Absence of tonic activity on an electromyogram and an often absent responsiveness to external stimuli are associated with REM sleep. Lower level tonic activity on an electromyogram and high-voltage, low-frequency waves on an electroencephalogra m are indicative of non-REM sleep.

Answer to Question 2

ANS: A
An electroencephalogra m shows that alpha waves and beta waves are present during wakefulness and diminish as the sleeper's electroencephalogra m converts to relatively low-voltage, mixed-frequency waves. Delta waves are present during slow-wave sleep or the deepest stages of non-REM sleep.
