to detail‚ and the ability to follow instructions for each soldier‚ and it provides leaders with an indicator of who among their soldiers actually is making an effort and who is just trying to do the minimum necessary to stay out of trouble. How crisp a uniform is pressed‚ how well boots are shined (when we had to shine them‚ the new boots don’t need it) placement of badges are all indicators of the effort someone puts in. Uniformity also helps ensure a comradery‚ and team environment. Everyone

Effects of Temperature‚ PH‚ boiling and concentration on Horseradish Peroxidase ABSTRACT The purpose of this report is to find out the effect of change in the Temperature‚ PH‚ boiling‚ concentration in peroxidase activity. Peroxidase is an enzyme that converts toxic hydrogen peroxide (H2O2) into water and another harmless compound. In this experiment we use‚ turnips and horseradish roots which are rich in the peroxidase to study the activity of this enzyme. The activity of peroxidase with change

experiment‚ I have been given a sample acid rain of concentration between 0.05 mol dm-3 and 0.15 mol dm-3 and my aim is to find out exactly what its concentration is. To do this I have been given solid anhydrous sodium carbonate and a range of pH indicators. With this solid anhydrous sodium carbonate I can make a solution of known concentration by mixing it with distilled water to make sodium carbonate solution (which is an alkali solution). Once I have mixed this solution I can use it to perform

However‚ complementary events‚ which have increased in regularity and severity‚ provide indirect evidence‚ which the increasing atmospheric concentrations of oxides of nitrogen and sulfur. These indicators include: · Mt Kilauea‚ Hawaii; released 350 000 tonnes of sulfur dioxide‚ annually since 1986 · Mt Pinatubo‚ Philippines; Spewed out 15-20 million tonnes of sulfur dioxide. · Pea-Soup Fog‚ London; 4000 lives claimed due to fog‚ high in sulfur

Research Question How will the addition of different pH buffers to amylase affect the rate of starch digestion measured using starch and iodine? Introduction Amylase is an enzyme found in human saliva and pancreas. It is the digestive enzyme that is needed to breakdown starch molecules. Amylase must be kept at certain conditions to function at its optimum level. This experiment will explore the effect of pH (1‚ 4‚ 7‚ 10‚ and 14) on the function of amylase by using starch and iodine.

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial
