The results of the statistical test did not support the hypothesis. The statistical test proves that the null hypothesis can be accepted regarding temperature impacting weight. However‚ we accept the hypothesis regarding conductivity. The test shows that the conductivity of a cell submerged in a solution can be altered with changes in temperature as the independent variable. However‚ the test shows that we accept the null hypothesis for weight change because weight is not impacted by temperature

In this study I am going to investigate the effect of caffeine on Daphnia (water fleas) heart rate. I shall use daphnia as they would never have been exposed to caffeine before‚ unlike a human‚ who may have already developed a high tolerance to it. Another reason is that Daphnia have a very translucent body; therefore‚ it is relatively easy to see their heart under a microscope‚ which makes it easier to count the number of heartbeats‚ thus‚ making my results more accurate. Hypothesis- Their

environment gave the participants no stimuli. This caused the heart rate slightly increase or decrease by less than 1.00 bpm. It is also possible that the heart rate of the participants had no change. The stressful environment presented multiple stressful and discomforting stimuli. These stimulates caused the heart rate to drastically increase more than 25 bpm. The difference between both environment’s completed means estimated to 45.00 bpm. This is a significant number in the greater sense that

Results During our experiment we were able to obtain data that showed that the raspberry had the highest DNA yield over all of the fruits at 1.93%. Our next highest DNA yield was at 1.11% and came from our blueberry sample. Although our blackberry had the third highest DNA yield there was a significant drop in our percentage to .921%. Based on our results the banana had the least amount of DNA yield with .138%. Discussion The purpose of this experiment was to be able to better understand the
