  • Catechol Oxidase Lab Report

    Methods: To conduct the experiment to see the effects of varying temperatures on catechol oxidase reaction time, multiple water baths were prepared at four temperatures: zero degrees, thirty-seven degrees, eighty degrees, and room temperature. The rate of the catechol oxidase reaction was measured by the use of a spectrophotometer. Next we gathered the materials that we need: gloves, spectrophotometer, outlet, eight test tubes, four test tube rack, ice, three thermometers, parafilm, masking tape, disposable uncalibrated pipettes, pipette pumps, kimwipes, a sharpie, absorbance conversion table, one percent cathechol, potato extract, DI water, two large test tubes and a timer. The two large test tubes contained potato extract and catechol. The control group was the blank test tubes, the independent variable was the absorbance rates, and the control variable was the temperature, volume, and pH. Gloves were used to prepare the blank test tubes by placing a label ‘blank’ on the tube. The solution contained 0.5 ml of potato extract and 5.5 ml of deionized water. The other four test tubes were prepared with 0.5 ml of potato extract and 5 ml of deionized water for each individual test tube and labeled one through four. The four new test tubes with 0.5ml of catechol were labeled C1, C2, C3, and C4. Finally, these eight test tubes were placed into a water bath and measured from lowest to highest temperatures. The test tubes were measured every five minutes, for example…

  • Temperature And Temperature Experiment

    an Erlenmeyer flask with an air sample will be placed in four different water baths, which vary in temperature. Following this, a mathematical relationship between pressure and absolute temperature of a gas can be determined. This data will be used to determine the type of mathematical relationship between pressure…

  • Crayfish Behavior

    while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five minutes and again for ten minutes. Once the time was up,we measured how long it took for the crayfish to lower their claws. By lowering their claws it represented them being calm. The…

  • The Negative Effects Of Nuclear Energy

    From the beginning, there has always been awareness of potential destruction. According to the Nuclear Energy Institute, there are 438 nuclear reactors that account for 10.9 percent of global electricity generation with 67 more plants under construction (“Nuclear Energy around the World”). In the aftermath of Three Mile Island and later Chernobyl, global safety precautions have gone into effect. The Convention on Nuclear Safety (CNS) was created between 1992 and 1994. Its aim is to legally force…

  • How To Win Friends And Influence People Analysis

    Look for areas of agreement. When you have heard your opponents out, dwell first on the points and areas on which you agree. Be honest, Look for areas where you can admit error and say so. Apologize for your mistakes. It will help disarm your opponents and reduce defensiveness. Promise to think over your opponents’ ideas and study them carefully. And mean it. Your opponents may be right. It is a lot easier at this stage to agree to think about their points than to move rapidly ahead and find…
