Answer

Brief Explanations:

The sentence contains a list of three coordinate adjectives (behavioral, mental, and physical) that modify the noun "changes." In English grammar, items in a series of three or more should be separated by commas. A comma is required after "behavioral." While the use of the serial (Oxford) comma before "and" is often a matter of style (such as APA or MLA), it is generally preferred in academic writing to prevent ambiguity. Therefore, a comma should be placed after "mental" as well.

Answer:

Circadian rhythms are behavioral, mental, and physical changes that occur on a twenty-four hour cycle.
