    Total CO2 Evolved by Different Concentrations of Convollaria roots. Actual values are the graduated pipette readings. For CO2 evolved values‚ subtract the initial reading from the actual reading. This is the amount of CO2 accumulated over time. | Time (min) | Tube 1 | Tube 2 | Tube 3 | Tube 4 |   | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved | Actual | CO2 Evolved |   | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | (A) | (A-I) | Initial reading (I) | 0.05 |   | 0

    Internment Camps vs. Concentration Camps There were two types of camps during WWII‚ internment camps and concentration camps. They each were created in a different place‚ the United States‚ and Europe. They have many differences‚ but also some similarities. Internment camps were created in the United States. They were created for the purpose of containing Japanese-Americans. The United States became fearful after Pearl Harbor got attacked by Japan‚ so they created these camps. The camps were like

    the Unknown Concentration of NaHCO3 (aq) Through Titration Introduction Titration is the accurate addition of a titrant- solution in a burette- into a measured volume of a sample (Kessel‚ 2003). There are many different types of titration‚ such as acid-base reaction‚ redox reactions‚ precipitation reaction and more (Dohrman). In this lab an acid base titration will be explored. In an acid-base titration‚ the concentration of an acid or base is unknown and is determined by the adding (from a burette)

    The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

    third reaction involves molecular iodine becoming a dark blue starch;I2(aq) + starch blue-black complex3. These three reactions react in a sequence. In any reaction the concentration is exponentially related to the rate of the reaction. The rate of the reaction is dependent on potassium iodate4. Therefore as the concentration increases‚ the rate of the reaction also increases. Since the rate of the reaction is inversely proportional to time‚ as the

    “Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews” (“Auschwitz”). Concentration camps were large numbers of people; mostly Jews enduring forced labor and mass executions. One of the concentration camps during the Holocaust was Auschwitz. Auschwitz-Birkenau had a unique design‚ a horrible daily life for those in it‚ and is greatly remembered for what happened at these camps at the end of the war. Nazi Germany set up camps with a specific design that would help them

    The Effect of Concentration‚ pH and Temperature on Enzyme Activity Biology For Majors October 4‚ 2012 Abstract We examined the reaction an enzyme has when its concentration‚ pH and temperature are altered. In order to do this‚ we added different levels of pH into different test tubes with the enzyme (sucrose)‚ and substrate (sucrose)‚ and we then inverted the tube. The higher pH produced more enzyme activity. Temperature effects enzyme activity by decreasing its stability when the temperature
