Gun Control And The Second Amendment - 922 Words
Gun control has been a long debate to determine if itââ¬â¢s better to have stricter access to firearms. America is one of the few countries that has gun rights embedded in their constitution. But what makes the US exceptional is that it has the right to keep and bear arms, other countries do not provide the right to have access to them, but rather, the government is allowed to regulate its use. The right to bear arms has also been the cause of growing violence and crime, at least according to anti-gun lobbyists. Citizens should be aware the dangers and harm that guns present to society. Controlling the sale of firearms can greatly decrease the number of violent crimes. Most pro-gun ownership often supports their argument with the Second Amendment. However, the Second Amendment to the United States Constitution doesnââ¬â¢t include or mention what types of firearms can be used for self-defense. It would be common sense to limit the sale of guns to handguns or small weapons to protect oneââ¬â¢s life. America has the Second Amendment mainly because of the history and itââ¬â¢s been a long tradition of the American people. And it has been further reinforced when the Revolutionary war began and armed civilians or militias won Americaââ¬â¢s freedom. People don t think about much of this history anymore, they care more for what the law states rather than how it got started or why itââ¬â¢s been implemented.

Intrisic Motivation Increases Student Achievement
Brief Review of the Literature Studies have indicated that intrinsic motivation increases student achievement. The success of integrating technology with increased student achievement could vary based on studentsââ¬â¢ intrinsic motivational styles. ATLAS has identified viable motivational styles within individual learning styles. Understanding different technologies and their effect on motivational styles in ATLAS has not been studied, but studies validate the importance and the need for this study.

This research is important to the proposed study because it indicates that student engagement can be increased if technology is implemented correctly. Ehrlich, Sporte, and Sebring (2013) reported the differences in technology use in districts in Chicago. The study found that 92 percent of students have access to the internet and technology at home. However, the frequency of use varied depending on the school that the students attended. Twenty to thirty percent of students used technology at school never or rarely. An inequality of technology exists between schools and schools that use technology. Schools that frequently use technology have higher achieving students. Enrich et al., (2010) stated, Technology use is ubiquitous in Americaââ¬â¢s colleges and most workplaces, and it is fast becoming accepted as fact that all studentsââ¬âelementary and high schoolââ¬âmust be exposed to technology (p. 1). This research is important to the proposed study because it indicates that the use of technology is inconsistent even when there is similar availability to technology. This research implies that researchers need to dete rmine better ways of implementing technology consistently.

Enzymes Lab free essay sample
Introduction Enzymes are protein based structures that help speed up chemical reactions. They help these reactions keep up with the everyday metabolic needs and other like functions of organisms. Enzymes are also considered catalysts, due to the lowering in activation energy, in which they are not consumed or changed at any point during the reaction. These enzymes have three main protein structures that help keep them formed and intact. Stage 1 of these structures is the primary structure, which is a unique sequence of amino acids. These unique sequences, when either folded or coiled into a chain, make up the second stage, the secondary structure. Once all these coils are folded into a three dimensional structure, the molecule is in the tertiary structure. These structures are all maintained by the formation of weak hydrogen bonds, and stronger covalent bonds. When enzymes are in the tertiary structure, they have the capability of having a specific substrate enter the active site. Once the substrate enters the active site, it forms a short transient stage known as the enzyme substrate complex. This is where, if the substrate(s) fit, the enzyme will produce specific product through the reaction process of catalysis. The enzyme being studied, catechol oxidase, is a common and well known enzyme that helps in the process of bruising and browning in fruits and vegetables (Danyk, 2013/2014). It is known as catechol oxidase because the phenolic compound, catechol, is being oxidized into quinones, in this case, benzoquinone. Enzymes activity is able to be sped up in many ways, including pH, increase in temperature, and the amount of substrate concentration. As the temperature increases, the rate of collisions between reactants also increases. This increase in rate affects the enzymes because the substrates move in and out of the enzyme faster, until the point at which a temperature will be too hot and it will rupture the bonds in potato juice being used. The acidity or alkalinity of a solution works in the same way, as high acidity or basicity will cause degeneration of the proteins as well. As forà substrate available, there will come a time where the enzyme cannot attach and release the substrates any faster, resulting in a plateau in the benzoquinone concentrations. (Danyk, 2013/2014) In our experiment we used potato juice extract to determine the influence of pH, temperature, and substrate concentration on the rate of enzyme activity. This being said, the increased speed of catechol oxidase should help produce higher concentrations of benzoquinone in the solutions. Methods and Materials The enzyme catechol oxidase was placed into a high speed blender to form a juice. All tests were watched for 5 minutes with gentle shaking at 1 minute intervals, and then placed into the 3à °C ice baths and arranged from palest to darkest. Tubes were placed into 3à °C ice baths in order to stop reactions. For the substrate concentration with 5mL of pH7 buffer was added to each of the six tubes. Respectively, 1, 2, 4, 8, 16, and 24 drops of catechol were added to each of the tubes. To equal out the amount of solution in each of the test tubes, respectively 23, 22, 20, 16, 8 and 0 drops of pH 7 buffer were added. 30 drops of potato juice containing the catechol oxidase enzyme were then added to the solution, and then timed for 5 minutes at room temperature. The pH treatment only required 5 test tubes, with 3mL of matching buffer (pH4, pH6, pH7, pH8, and pH10) in the appropriate tube. Following this, 10 drops of both potato juice and catechol are added to the tubes, and then timed for 5 minutes at room temperature. For temperature, 6 test tubes were required, and placed in their appropriate temperature treatments all with 3mL of pH7 buffer in them. These tubes were place in either 3à °C, 12à °C, 20à °C, 35à °C, 50à °C, and 70à °C baths for 15 minutes to warm each tube up to the appropriate temperature. After the 15 minutes, 10 drops of both catechol and potato juice are added to each of the pH7 solutions. After arranging all the solutions from palest to darkest in their respective treatments, the spectrometer would be needed. Starting with the palest and moving to the darkest, all absorbance was measured at 460 nm. Once all theseà readings are found, divide by 0.0078 to calculate the benzoquinone concentration (à µm). Mean and standard deviation were both calculated using Microsoft Excel 2007. Results Based off the class date and the means calculated, it was found that all treatments had a point in which there would be no more benzoquinone released due to bonds breaking. The trend found when working with the amount of substrate availability showed a gradual plateau at concentration of about 85-90 à µm (Figure 1). But based off the data collected, until this point, amount of substrate available did have an impact on how the concentration of benzoquinone. After the results were calculated, there was a peak at which it had the highest concentration of benzoquinone, pH7. As the pH got lower, so did the benzoquinone concentrations. As well, when the pH got higher, more bonds would degenerate, causing the benzoquinone concentrations do be lower (Figure 2). The results were seen and could be predicted as to almost be a bell curve trend. Temperature had almost the same effect as pH did. When the temperature reached a certain point, bonds started to be broken throughout the reaction. This caused almost a bell curve in the results. The point at which the highest benzoquinone concentration was found was at about 15 20à °C (Figure 3). Even though the class data pointed out there was a higher concentration at about 70à °C, in general there was a bell curve to the results.

Bars above and below represent the standard deviation for the class. (n=6) Discussion The results seen during this experiment supported the hypothesis that temperature, pH, and the amount of substrate available all increase the rate of enzyme activity. This is proven by the results discovered in the reactions done. During the reactions, after putting them through the spectrophotometer, the results matched that all treatments would increase the rate at which catechol oxidase works. Both temperature and pH showed a peak before dropping again after a certain point, and the amount of substrate availability showed a gradual plateau. As temperature increases, so does the frequency of the at which substrates collides with active sites. This is due to the increased rapid moving of the substrates. Once the temperature reaches a certain point, in this case about 15-20à °C, the temperature actually starts to rupture the weaker bonds in the active site. This is why there is the drop in the benzoquinone concentration (Reece, 2011). However, in the graph, there was an unexpected result found at the reaction at 70à °C (Figure 3). This result was not seen to be possible, but it was evident that at the 2 tables, due to the cloudyness of the reaction, more light was absorbed in the spectrophotometer. Both the pH reaction and the amount of substrate available both agreed with the hypothesis given, and followed the trend lines expected. No unexpected results came from these 2 reactions. Both these reactions followed different trend lines, due to the effects of the treatments. PH was able to degenerate the ative sites, where as the amount of substrate just made it too much to actually coninue the reation any faster. Thats why there is a plateau when working with the amount of substrate. PH also works the same as temperature, where all enzymes work best at an optimal pH. Most enzymes work best at an optimal pH of 6-8. Beyond these optimal pHs, the active site usually degenerates, and in this labs case, they did degenerate, leaving a peak and drop in the reations. To conclude, with the exception of the skewed result during the temperature readings, all three followed the general and predicted trend lines of the reaction. And with the reactions following the proper trend lines, it is evident that there is an understanding of how temperature, pH, and amount of substrate available affect the rate at which enzymes work Literature Cited Danyk, Helena. 2013.
