Answer 1

Answer: C. the circadian rhythm.

Explanation: The circadian rhythm refers to a set of natural or physiological processes which an individual experiences within a 24-hour cycle. The circadian rhythm is exemplified in processes such as changes in energy level, when an individual has a weary feeling at night and renewed vigor when awake in the morning. Light-related circadian rhythm is highlighted in the sleepy feeling inherent in animals at night and being awake during the day,thus is the sleep-wake cycle. Other instances of circadian rhythm include changes in body temperature, hormonal release and so on.

Answer 2

c. the circadian rhythm

Step-by-step explanation:

Circadian rhythms can be defined as physical, behavioral and mental changes that follow a daily cycle. Circadian rhythms primarily respond to light and darkness in an the environment of an organism.

Being awake during the day and sleeping at night is an example of a light-related circadian rhythm. Circadian rhythms are mostly found in living things, this includes animals, plants, and many tiny microbes.

Chronobiology is the study of Circadian rhythms.

The feeling of energy during the day and having a tired feeling at night is an example of Circadian rhythms.
