... themselves from rotting and bacteria. (Wegener, 2002) In this experiment we focused on the effect enzyme concentration, substrate concentration, temperature, and pH, had on the enzyme activity of catecholase (in this experiment potato juice was used). We hypothesized that changing the temperature and pH from within the optimal range would disrupt the reaction. We also hypothesized that because ... 8, or 10. The 5 experimental tubes were prepared in the same method as the blanks except 1mL of catechol was added instead of the1mL of water. After letting the tubes stand for 5 minutes (mixin...

... close with the theoretical values; the du/dV and du/dU values were almost exact, with the errors in the order of 1.1%. The greatest percentage error was given by the dv/dU value of 3.8%. The differential values were taken (experimentally) from graphs, where values will always differ depending over which region you determine the slope, this is obviously expected and trivializes the errors ... . The position of the principal axis was determined as being (experimentally) 22.78o and 23 .37o (theoretically) {as shown in Fig.1-appendix}, with ... ), it is most likely the former. However I can'...

... (1250 bytes). The interarrival time does make a noticeable change to the load of the network when the size of the file is relatively low (625 bytes). The lower the interarrival time, the lower the load on the network. The following are graphs produced from the results collected from experiment 1. Average number of collisions in the network End-eto-end delays compared to interarrival time ... The average number of transmission attempts Utilisation compared to the interarrival time in the network For the second part ... collisions in the network and altogether less network load. The graph...

... likely to stop the electrons from passing (it's resistance goes up). We found this out from carrying out a practical experiment on the characteristics of a bulb. We couldn't make the supply voltage too small, as our meters would not have been able to record the results because they ... circuit to be measured. Conclusion In my prediction I stated that, if the length of the wire increases, then the resistance would also increase in direct proportion to length. In the graphs, which I produced, I can see that the resistance of a wire is in proportion to the length, as I predicted. I know ....

... we did in order to investigate the enigma known as the Coulomb balance. We began by using the apparatus shown in Figure 1. This coulomb balance consisted of a torsion balance made of fiber (A), a counter weight, damning vane, and a rod. The sphere b, when charged, would exert a force on sphere a, causing it to spin ... checked one more time by sliding sphere b into position where it barely touched sphere a, and the reading on the scale was 3.8 (the diameter of the spheres), meaning that in fact we had set the apparatus correctly. Following this joyous finding, we then charged the spheres...
