Question

Does anyone know an animal that has developed multiple responses to a varying degrees of a single stimuli?

Answer 1

By degrees do you mean angles?

Answer 2

by degree he means dimensions

Answer 3

cats and dogs both are in this category

Answer 4

I am not an expert, but if you wanted a specific example - I believe one which has been scientifically well studied (so lots of available reference material on it) is the response of fruit flies, Drosophila, to various smells and scents. In this case scientists have gone to some trouble to understand the actual biochemical mechanism - which proteins are activated, what signalling pathways they affect, what genetic responses are triggered and how those genetic responses affect behavior of the fruit flies - through which the stimulus affects the fruit fly. So it might be worth looking into. Best of luck.

Answer 5

I am going to assume you mean chemical stimuli? A fairly simple answer would be human - we have numerous mechanisms where the amount of stimuli directly effects the body response. An example I can think of that is most obvious is when your physical exercion reaches a certain level your muscles will switch to anaerobic pathways to keep up with the oxygen demand. But I agree with the above answer, there is a LOT of studies published about Drosophila - you can also look at other commonly studied animal models such as mice or rats...
