condition (listed from left to right in the table) ranged from: 19.6-59.2%‚ 11.8-76.0%‚ 25.0-92.3%‚ and 12.5-89.8%‚ respectively. From this‚ we can generally see how the data from each group is spread out across each ligation condition. Table 2. ANOVA test results. The p-value corresponding to the F-statistic is lower than 0.05‚ suggesting that one or more treatments are significantly different. We can see that the treatments that are significantly different are the 1:1 with stuffer and 2:1 without stuffer

After conducting the trials for each beaker and each bag my hypothesis of each of the trials were correct. Every outcome I predicted occurred to each beaker and each bag. Beakers 1 and 2 decreased in mass while beaker 3 stayed constant. Beaker 4 actually increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials. Above you can see a specimen of an

After distributing the Stroop Task‚ the following results were discovered: the mean for the musicians was 1178.7070 milliseconds and the total mean for the athletes was 1235.188 milliseconds. Our results was the following‚ t(18)=0.587; p=0.567. The results as demonstrated can clearly state that there was not a significance within the .05 alpha level. Therefore‚ the null hypothesis had to be retained. Our conclusion of the Stroop Task was that the musicians did not show a faster (lower) time in comparison

As a result of the tests ran‚ I was able to identify the unknown bacteria. For Unknown A‚ I ran six tests. I first isolated the bacterium from the second bacterium and found a clear growth (Table 1‚ Figure 1). Secondly‚ I ran a gram stain and found a gram positive‚ cocci bacterium (Table 1‚ Figure 2). Third‚ I ran a catalase test in which was negative (Table 1). From here‚ I determined a starch hydrolysis test would be necessary to distinguish between different bacteria. The result was negative (Table

10 Test Tube Mystery Introduction: The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4‚ NH4Cl‚ NaOH‚ AgNO3‚ KI‚ H2SO4‚ NaBr‚ CaCl2‚ HCl‚ and Pb(NO3)2. The students are expected to determine the chemicals using physical properties‚ litmus paper‚ solubility‚ and the process of elimination. Physical properties‚ such as the color‚ can be determined by sight. Litmus

In this lab‚ we tested the effect of flame on different chemical solutions. In order to do this‚ we used a wooden stick soaked in a metal and nonmetal solution‚ hovered it over a bunsen burner‚ and recorded the color that the flame changed to. The seven solutions we tested were lithium chloride‚ strontium chloride‚ calcium chloride‚ sodium chloride‚ barium chloride‚ copper chloride‚ and potassium chloride. However‚ we had another four additional solutions‚ which had unknown chemical composition

specially. This funnel is called as V-funnel. This test is a self-compactibility test to measure the capacity of concrete to pass into the spaces. This test determines the viscosity and passing capacity of SCC. Fresh SCC is filled to the funnel without any compaction or vibration and then the sliding cover under the funnel is opened and the filling time of all concrete in the funnel to the pail is recorded. Fig. 2 V-funnel test L-box test L-box test is used to assess the passing ability of SCC to

This lab was conducted to physically see the breakdown of carbohydrates into simpler sugars (glucose‚ fructose‚ galactose) using the salivary amylase enzyme. This is extremely important to all metabolic functions in the human digestive system. It
