Question

Quizplus · Accepted Answer

The definition of sleep is best represented by option B: a periodic natural loss of consciousness that involves distinct stages. While the other options mention certain aspects of sleep, they do not fully encompass the complex nature of this phenomena. Option A may describe circadian rhythms, which are important in regulating sleep, but do not fully define sleep itself. Option C may describe a type of deep sleep, but not the entire sleep process. Option D seems to reflect the symptoms of a sleep disorder, but not the definition of sleep itself.
