The California worm was a very interesting organism, its skin was transparent which helped us all/apeezy students find the pulse. although i'm pretty sure there was lots of mistakes, some may have counted the blood flow instead of the heart pulse, maybe some of us didn't get an exact number due to the worms squirming all around making it very difficult to keep track of the pulse. less likely would there have been a precise number through out the lab. Although it was definitely a frustrating lab due to knowing if there was a precise number, we did our best to do our calculations. For solution A we got an average number of 41.6, solution B we calculated 57 and lastly solution C had the mean of 37. With that being said, my answer would be that solution A is the neutral water as for solution B would be the stimulate and, solution C would have had to be the stimulate solution.
