Temperature and Substrate Concentration on Catalase Kristen Clark Biology 101 Lab Section 041 9/22/14 Brandon Stroup Abstract Catalase is an enzyme found in every living organism and is essential for cells. This lab explores how catalase reacts to four different temperatures and how the concentration percentage of substrate affects its reaction rate. The performance of catalase is dependent on many factors, so the purpose of the lab was to find the ideal concentration and temperature for…

they are for that future, and also that they like to have fun. It shows that it is possible to have fun even in such harsh conditions, especially during the Holocaust. Frankl explains, "Yet it is possible to practice the art of living even in a concentration camp, although suffering is omnipresent. To draw an analogy: a man’s suffering is similar to the behavior of a gas. If a certain quantity is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the…

they or anyone else did not deserve to be treated horribly. “Mr. Frank of course I will help but no one may find out it has to be in secrecy.” As I walked back to my home all I could do was think about the terrible fate many Jews faced in concentration camps. When I arrived home the first thing I noticed was the aroma in the house. It smelt of…

Dachau, Germany, not more than a few hours ago. The Germans had been out of the area for at least a few days, and we had come to investigate the area and search for a concentration camp said to be located in the area. Truthfully, more than anything, I was curious as to what could be here. I had heard stories about the concentration camps; their gas chambers and medical experiments. In the two years I’d been in the army, I hadn’t seen one. In those years I’d seen plenty, enough for a lifetime,…

was a boy.” This passage is significant to the plot because the boy, Shmuel, and Bruno became very close friends, but the only thing separating them is an electric fence. Bruno’s father is a very respected Commandment in charge of the Auschwitz concentration camp. In the book Hitler himself and his girlfriend had dinner with Bruno’s father and mother. This passage is significant to Bruno because this little event leads to his death at the end of the book. This passage made me feel shocked and…

added to this solution giving a partial suspension of pH 9.8 without modification. separate flasks each of which contains 1% K-humate solution in dist. H2O. The mixture was shaken at room temperature, left for overnight, and then filtered and the concentration of soluble Si and Fe was measured in the filtrate by Inductively Coupled Plasma Spectrometry (ICP-Ultima 2 JY Plasma).ICP-Atomic Absorption Spectrophotometer (ICP-AAS). Total soluble Si and Fe released from both minerals and in humate…

activity of the volatile extracts on C. nearcticus at five concentration points after 180 minutes of exposure time. At 5% w∕v concentration, C. sinensis recorded the least activity of 22% toxicity whiles C. aurantifolia recorded the highest activity of 50% toxicity at same level of concentration. C. limon and positive control had 36% toxicity at this 5% w∕v level of concentration. C. Aurantifolia and C. sinensis levels out at 10% w∕v concentration and a sharp rise to over 90% toxicity. C. limon…

Market concentration is the extent to which, relatively small number of firms account for relatively large share in the market. In other words, it is the degree of monopoly power exercised by few firms. Alternative terms for market concentration are industrial concentration or seller’s concentration. Market concentration is considered as an important aspect of market structure as it reflects the market power and hence firm behavior and performance. Research Problem Probing into the existing…

different concentration camps that Hitler used to put the jews in. But one that stands out is the Dachau concentration camp it stands out the most because it was the first concentration camp that Hitler built. There is also a lot of history on the weapons or strategies they used to kill the prisoners there and how much food did the prisoners get in a day. Another is how much people even survived, did the prisoners ever get treated when they were sick or injured? The Dachau concentration camp was…
