AS Biology Beetroot

My Evaluation I have plot all triple repetitions aboard one another to try to see if in that location argon any app arent anomalies. I am now loss to work out the nastys of the results that I obtained, by adding up all the colorimeter readings for each temperature and then dividing them by the fig of results that I use, and then plot these results against the like temperatures. Mean 26°C = 0.022 + 0.115 + 0.065 = 0.066 3 Mean 36°C=0.166 + 0.201 + 0.103 = 0.157 3 Mean 40°C=0.186 + 0.218 + 0.187 = 0.197 3 Mean 56°C=1.102 + 1.465 + 1.739 = 1.435 3 Mean 62°C=1.283 + 1.898 + 1.932 = 1.704 3 In my graph of mean values plotted against the corresponding temperatures, you can see that from 26°C 40°C the strain is fairly flat and rising tardily and steadily. later on 40°C the gradient of the line becomes sheer and the line begins to curve. My graph does not plateau, although it may have through so if hig h temperatures were available to me. From 26°C to 40°C there is a gradual increase in the absorbency, which indicates that it is because of of course occurring dispersal.

Diffusion of the pigment happens because the concentration of beet pigment is higher within the cell than outside the cell. So airing occurs atomic reactor the concentration gradient, from an land of high concentration to an area of get off concentration, across the partially permeable membrane of the beetroot cell. As the temperature increases the molecules within the beetroot are given to a greater extent kinetic energy and thus the process of diffusion is sp eeded up. From 40°C to 62°C there is a ! sudden increase in the absorbency reading, which indicates that the cell the cell walls of the beetroot are being denatured. For example, at 40°C the mean absorbency was 0.197 compared to the 62°C were the mean absorbency was 1.704. as the temperature rises above 40°C, the vibrations caused by the increasing temperature provides more heat...If you want to get a beat essay, order it on our website: BestEssayCheap.com
