Effect of Temperature on Peroxidase Ability to Break Down H2O2 By: Rodneika Crutcher Abstract Temperature affects the ability of peroxidase to break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase

Starbucks drink sizes （这是第一部分） Demi-3 oz(89ml) The Demi size is the smallest size at Starbucks‚ and is used to describe an espresso drink size. Short - 8 oz(240ml) It’s not very commonly ordered(even though it’s a completely normal amount of coffee to drink at home)‚ and you can only get hot drinks in a Short size. Tall - 12 oz(350ml).

Remove specimen A from the test machine and place specimen B in the compression press machine [see “picture.pdf” on Learning Central]. Increase the load until failure occurs (typically‚ go up to around 500kN). Note the maximum load‚ and the shape and sizes of specimen B after the test. 3. [Watch Clip 3] Place one of the concrete cubes in the compression press and measure the shortening of the specimen with a dial gauge for increasing load. Remove the dial gauge and test to failure‚ recording the

There are many impacts that could affect the academic achievement .one of them is reducing class size. Based on the work of a group of researchers headed by Gene Glass and Mary Lee Smith‚ 15 students was chosen to be the number of students in small class size for the major benefits to be obtained (Glass‚ et 1978).It is suggested that reducing class size by five student is expensive but it is not found to be as costly as lengthening the school day or using computer assisted instructor. It can have

Ventilation and Oxygen Consumption in Fish Sally Ming Bio 102- PR# 2 12/12/12 Abstract Goldfish (Carassius Autarus)‚ when subjected to warm temperatures will have a high rate of ventilation compared to those exposed in colder environment. In a class experiment‚ we observed and recorded the effects of water temperature at [25 C] warm and [15 C] cold on ventilation and consumption rates in goldfish. For one hour at 15min intervals we observed differences in both ventilation and consumption

Bread Mold Experiment By: Stephanie Westover PURPOSE The purpose of this experiment will be to determine how temperature affects the growth of mold on wheat bread. The researchers choose this topic because she thinks it will be beneficial to find a way to keep food from molding. Determining how long bread can be stored before molding can help save money‚ prevent illness and preserve freshness. The question the researcher will attempt to answer is how freezing

Size Exclusion Chromatography Size Exclusion Chromatography (SEC) is the separation technique based on the molecular size of the components. Size exclusion chromatography is a kind of method to separate different size of molecules that put in solution. It was first discovered by two scientists who named Grant Henry Lathe and Colin R Ruthven. Both of them received the John Scott Award for this fabulous invention. There are various applications for Size exclusion chromatography such as biochemical
