What are circadian Rhythms quizlet?
What is the circadian rhythm? The biological clock; regular bodily rhythms (for example, of the temperature and wakefulness) that occur on the 24 hour cycle.
Do mice have circadian rhythms?
Mice as nocturnal creatures are active mainly during the dark phase. This property is maintained under free-running conditions (i.e., constant darkness), when its endogenous circadian clock dictates the behavior of the animal, devoid of all external timing cues.

What are circadian rhythms regulated by?
What are examples of zeitgeber?
Zeitgebers are cues given by the environment that reset the circadian rhythm. These cues literally impact the expression of our genes. The science of this process is called chronobiology. Examples of the key zeitgebers in humans are environmental cues like sunlight, exercise, and eating.
Do dead mice deter other mice?
When a rodent is killed by a mouse snap trap, or an electric mouse trap, if the mouse lies for perhaps a day or so before being removed, the smell of the dead mouse can be very strong to other mice. When you bait the trap again, other mice may sense the dead mouse smell and be repelled by it.
