... . Each time stentor would cross a millimeter mark, it would be counted and added to the data. The number of lines crossed was counted in one minute for each temperature for three separate trials. The results were gathered, analyzed, and plotted on bar graphs along with charted T-tests. For each graph the mean, range, and standard deviation were calculated and for every T-test ... the probability was calculated. Results The analyzed data suggests that an increase in temperature of the environment causes an increase in movement of stentors. Referring to figure 1 and figure 2 bar graphs, ou...

... three fuels to see which had the highest temperature. These fuels were hexamine, candle and a paraffin lamp. I did this experiment by putting a beaker of water (200ml) over the burning fuel and recording the initial and final mass. The temperature was risen 20c and using the results we found the temperature ... rise per gram. This helped design this experiment because it has the same idea of a beaker over the burning fuel. The difference is that we are seeing the heat given off by the Bunsen burner flame and not the ... measure the temperature while we are experimenting with the heat. ...

... interact at a specific active site on the enzyme, forming a temporary enzyme-substrate complex. However it is now clear that the active site of some enzyme molecules change shape when the substrate molecule attaches to it. This is known as the induced fit model'. When the substrate molecule ... are polysaccharides which form the support matrix in the plant cell wall structure. The pectins are broken down through hydrolysis into shorter molecules of Glacturonic acid; the acids can then be broken down further into other compounds such as sugars. Pectin is undesirable in fruit, their ... ...

... and so confirms that pressure increases uniformly with volume. The graphs do not pass through 0 Celcius, instead (if the line is retracted back), they intercept x (temperature) at -273 C. This is known as absolute zero, and is known as 0°C on the Kelvin temperature scale. Charles' Law The volume of a fixed mass of gas is directly proportional to its absolute temperature if the pressure ... five other points were noted between these two temperatures. This should provide is with enough information to use graphs and will make any anomalous results easier to see, as they will be out of the...

... that there were no females or because they were under stress. (http://www.msue.msu.edu/msue/imp/mod02/01500542.html). Our poster contains graphs that show how much male crickets chirp in 0C and 40C, and also the chirping at 25C, which was our control group. Our hypothesis ... uk/bugclub/cricket.html). The calling sound is basically the conspicuous chirping sounds made by males. Past research showed that male field crickets produce three types of acoustic signals: aggressive chirps, which are used in male-male fights; calling songs used to attract females; and courtship song, used directl...
