|
|
|
Phase shift |
The amount if time difference between an entrained endogenous biological rhythm and the same rhythm when the zeitgebers have been removed |
|
|
|
Sensory receptor |
Any part of an organism capable of detecting a stimulus and sending a signal to another part(s) of the organism. |
|
|
|
Taxis |
Innate behavioral responses of an organism resulting in movement in response to stimuli such as light or the presence of food |
