California Black Worms

               
     
              Thoughtout my research I believe that the three water substances were plain, stimulant and depressant. After analyzing the data I believe that water A was the plain due to the low numbers of pulse rate. Water B was the stimulant since it was stable. C would be the depressant, The depressant has parasympathetic responses, in similarity to the worms. The black worms were not stable and had an odd value of pulse rate compared to the one before. I came to this conclusion thanks to the data we collected in class and resources proved online.
