Sweet Potato Pie Eugenia Collier From up here on the fourteenth floor‚ my brother Charley looks like an insect scurrying among other insects. A deep feeling of love surges through me. Despite the distance‚ he seems to feel it‚ for he turns and scans the upper windows‚ but failing to find me‚ continues on his way. I watch him moving quickly—gingerly‚ it seems to me—down Fifth Avenue and around the corner to his shabby taxicab. In a moment he will be heading back uptown. I turn from the window

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

13‚ 2013 Determining the Concentrations of Red Dye in Sodas Abstract The use of red dye #40 is common in various soft drinks today. The labels on these beverages do not specify how much dye we are consuming. We did this experiment to find out which soda uses the most dye. Using a spectrophotometer‚ we measured how much light is absorbed by various known concentrations of red dye. After collecting this data‚ a standard curve was made that correlated the concentration of red dye #40 to its absorbance

Phenolase and Peroxidase from Sweet and Irish Potato Hypothesis: Polyphenol Oxidase enzyme activity can be detected by change in colour of solution‚ Inhibitors prevent the reaction of the enzymes with substrates‚ the enzyme is relatively specific. Aim: To design and conduct an experiment to demonstrate enzyme activity of Polyphenol Oxidase and Peroxidase when mixed with catechol‚ caffeic acid‚ pyrogallad‚ tyrosine‚ guacol‚ and water‚ to test the effect of inhibitors on these enzymes‚ to show the

There are numerous concentration camp that were constructed across Nazi Germany from 1939-1945. During this time period‚ Jews‚ gypsies‚ homosexuals‚ and bountiful of others forced by the Nazi regime to these concentration camps. There were countless experiments performed on those who were in certain camps‚ but mostly forced labor to build items for the German army. Of all of these camps one was the most notorious‚ which was Auschwitz concentration camps. This camp was the largest of its kind‚ but

Purpose: To find the percent of sugar by mass in chewing gum Hypothesis: The percentage of chewing gum that is sugar for bubble gum is 30%‚ 20% for juicy fruit and 25% for stride gum. Mass Of Juicy Fruit Mass Of Bubble Gum Mass of Juicy Fruit unchewed | 7.12g- 1.72 = 5.4 g | 5.80g- 1.72g = 4.08 | 4.52g- 1.72g = 2.80g | chewed | 3.00g- 1.72g= 1.28g | 2.24g-1.72g =0.52g | 2.86g-1.72g= 1.14g | Percent of Sugar | 3.00g x 100/ 5.4 = 55.5%

No; the experiment was not successful‚ because it did not show the correct fluorescence gradation of the serial dilution of the DNA concentration. As shown by the picture‚ only the first drop of the DNA/EtBr mixture for the DNA standards fluoresce brightly under the UV light‚ while the other spots for both the DNA standards and the unknown DNA standards were all dimly fluoresce. This was due to pipetting error; the tip of the pipette did not touch the liquid (TE) in the micro-centrifuge‚ so no DNA

The concentration camps was a place where people were detained and confined. The concentration camps are where they held jewish people against their own will. The concentration camps was where the Germans placed the Jews to hostage before killing them. There are three specific concentration camps that the Jews were sent too. The three concentration camps were the transit camps‚ forced labour or work camps‚ and extermination camps. Adolf Hitler just wanted to prove his power to everyone. The
