From the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes. Figures 1-3, 5-6, and 8-9 all showed a change, but not as large as their counterparts. This was due to the fact that the mice were usually cleaning themselves at in this group during the control. Figure 8 shows the smallest change between the two groups with a value of 0.0002. This figure represents a Cage A Yellow Mouse, which also had one of the lower body weights. The statistics from Tables 1-3 we were able to find the amount of CO2 produced in mL for each mouse as seen in Table 4. These statistics …show more content…
Using an online program from Vassar Stats we were able to calculate the statistics necessary for our experiment. The Two Sample t-test program was initiated on the website, and using the data from Table 5 the program was ran with the Correlated Samples option selected. This was selected due to the fact that the mice from our control group were also used in the experimental group. All of the information provided by this tool can be in Figures 10-12. The major value from all of this is from Figure 11 and it was our two-tailed P-value. This value was 0.019589 and with this statistic we were able to look at our hypothesis again. We could successfully conclude that our null hypothesis of the urine having no effect on the mice was wrong. This is because of P-value is <0.05 and represents that are data was statistically
From the above data, one can see that the greater the concentration of caffeine in the water applied to the Daphnia, the higher the average heart rate in beats per minute of the water flea. For example, at 0% concentration of caffeine the average heart rate of the Daphnia was 165 bets per minute however you can clearly see a difference in heart rate with the Daphnia when placed in a 0.5% caffeinated solution as the average heart rate was 268 beats per minute. An increase of 103 beats per minute on
Modeling is an important tool to test if the reintroduced animal has a chance to succeed and thrive in an area where it vanished. Factors that we now know can be but into that model, such as the relationship that the lynx has with its keystone prey, the Snowshoe Hare (Lepus americanus). Prey abundance is an important factor in the predator – prey relationship of the lynx and hare. Studies have shown that for the lynx to succeed there needs to be a hare population of 1.1 to 1.8 hares (Steury, 2002) The next set of studies that went into the success of the lynx was the study that took into account that the lynxes chooses a habitat that best suits its prey.
Mus Musculus belongs to the Mammalian class of vertebrates. A common and advantageous characteristic of the house mouse is its relatively small size. At birth, mice have an average weight of 1 gram. Peak weight ranges from 25-40 grams in adulthood. The reproductive biology of mice is especially conducive for laboratory breeding.
My hypothesis was supported by the experiment. The goldfish’s respiration rate slowed down as the temperature of the water was lowered. The independent variable of this experiment was the temperature of the water, and the dependent variable was the respiration of the goldfish. When the goldfish lowered its respiration rate it did not intake as much oxygen. Without as much oxygen, the goldfish used less energy.
How long did it take for the populations to evolve into different populations with different colored coats? Did gene mutation cause a change in the coat color between populations of the Rock Pocket mouse? Hypothesis: Alternate hypothesis: Rock Pocket mice have different coat colors that help to their advantage that depend on their location through evolution. Null hypothesis: Rock Pocket mice don’t have different coat colors that help to their advantage that depend on location through evolution.
Although in the first three experiments we had positive results to support our hypothesis experiment four contradicted it. There was in no way that we could prove that the temperature of the snails environment effects their movement depending on if they were in small or large
After analyzing all the raw data, and doing even more calculations. I can definitely say that, there are some trends and correlations in this study. Comparing and contrasting both the data of the nutritional contents, and my raw cumulative data of ten trials for each drink, helped find these many correlations and trends. Starting off, for Mouse #1, the sum of the baseline data, which was 10 trials, equaled to 5950.13 cm.
After reading the article I discovered that the results from my experiment were highly correlated to the experiments that were conducted in the article by authors Brennan Davis and Collin R. Payne.
Question Does creatine supplementation increase maximal strength? Hypotheses Null Hypothesis- Creatine supplementation has no effect on maximal strength. The mean difference of the paired groups is zero.

As we all know, the structure of human body is extremely complicated with eight systems and thirty-six essential organs. Hence, human have difficulty applying their research results on human body even with accurate computer simulation. “It is possible to do basic tests on cell lines but this does not replicate the complex interconnected processes of a live body and can never predict potential side effects on different organs within the body”(Anderson). In addition, animals, especially mammals, share a common ancestry with human being in fact, thus their organs, nervous system and other constructional details work similarly as human body does. “The DNA of mice is 98% similar to that of humans.
Put all the mice back into their tanks for the night. The next day, repeat the steps involving the chamber and Micro-Oxymax software. Take the data from before the hormone injections for the male mice and compare them to the data collected after the injections. Find the t-value and p-value and test the hypothesis with a significance level of 0.05. Do the same for the female mice and reject or accept the null
The error bars on the graph show little overlapping of data, indicating that the data are somewhat reliable to a large extent. Analysis of Mammal Tooth Mass Loss in Coca Cola Results show a negative correlation (Table 7 & Graph 2) between concentration of Coca Cola and the percentage mass loss in each tooth. Looking at each individual data points, although the points may not all lie on the line of best fit, however the percentage mass loss in 20% is the highest amongst all the other points, while being lowest concentration within the experiment, therefore, supporting the argument that there is a negative correlation between the two variables. The R2 value is less than 0.5, suggesting a non-linear relationship between the two variables. 2.1) Material Deposited on
Last step, you make a decision. To make a decision about the null hypothesis you use the value of the test statistics. The researcher can either reject the null hypothesis if the mean is associated with a low probability of occurrence when the null hypothesis is true; or he can accept the null hypothesis if it has a high probability of
