Quizplus · Accepted Answer

The lizard's bobbing dewlap is a signal, as it is a visual cue that the lizard is attempting to communicate something to others of its species. A stimulus is something that elicits a response, and a reflex is an involuntary response to a stimulus. An innate releasing mechanism is a neural circuit that is hardwired to produce a specific behavior in response to a specific stimulus.
