For safety precautions, safety gawk were worn. passim the experiment, there were a number of observations made: 1. At the start, the subterfuge of the 0 percent cider solution was a precise light brown colo r. The 50 percent cider solution had a mediu! m brown color, and the 100 percent cider solution had a dark brown color. 2. At the cardinal minute mark, the yeast cells were still pretty equally distributed passim the cider solution. 3. After 17 minutes and 30 seconds, the balloon of the 50 percent cider solution was stand flat up and was completely filled, while the other 2 solutions were 0 percent...If you want to get a full essay, piece it on our website: BestEssayCheap.com
