Which of the following best describes the circadian rhythm?
A
the pattern of emotional ups and downs we routinely experience
B
a pattern of biological functioning that occurs on a roughly 24-hour cycle
C
the cycle of five distinct stages that we experience during a normal night’s sleep
D
None of the above
Explanation: 

Detailed explanation-1: -Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes. Chronobiology is the study of circadian rhythms.

Detailed explanation-2: -Circadian Rhythm and Chronobiology of Sleep The termcircadian rhythm originates from the Latincirca, meaning “about, ” anddies, meaning “day.” Human circadian rhythm generally has a cycle length close to 24 hours (approximately 24.2 hours) (Czeisler and Gooley, 2007).

Detailed explanation-3: -Circadian rhythms are 24-hour cycles that are part of the body’s internal clock, running in the background to carry out essential functions and processes. One of the most important and well-known circadian rhythms is the sleep-wake cycle.

Detailed explanation-4: -The length of the rhythm is not only longer than the intrinsic 24.2-hour cycle of the SCN, but may be up to 25 hours or more in length. This is because self-selected light exposure late in the day has a delaying effect.

Detailed explanation-5: -Circadian rhythms have an important purpose: they prepare your body for expected changes in the environment and, for example, the time for activity, time for sleep, and times to eat. External cues are important; the strongest is the sun’s light/dark cycle.
