CAT - Measuring the pH of common household substances 1. Predict the pH value of substances & estimate the pH value by using the universal indicator. 2. Use the indicator to identify acidic‚ basic‚ and neutral substances found in any home 3. Classify household items as acids and bases 4. Collect organise and analyse results in tables and graphs (if necessary) 5. Analyse results and explain the reason the substances have the pH obtained. Aim – To use a universal

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

| Economic Activity Economics is concerned with humanity’s well being or welfare. It encompasses the social organization and the relationship involved in using scarce resources and available technology to satisfy seemingly unlimited human wants and in allocating those resources among diverse alternative wants. The key elements of economic activity are (1) human wants (2) resources‚ and (3) technology. Price theory (microeconomic

Monica Mahmoudi 02072798 Bandaruk Mon-Wed 12:45 PH Balance in the Human Body As we all know every solution is either acid or alkaline. Alkaline is often called base. These solutions can be anything from body fluids‚ to fruits‚ vegetables‚ seawater‚ beverages you name it. Acid and alkaline is measured in pH. It starts as low as zero being very acidic and works its way up to fourteen being the most basic. The pH of our stomach is 2‚ obviously to digest food‚ wine is 3.5‚water is 7(neutral)‚ arterial

for a grittier realism that sometimes works. “Paranormal Activity” succeeds with flying colors. It’s a brutal‚ exhausting‚ and genuinely horrifying little ghost flick that really makes me rethink my stance on horror films altogether. “Paranormal Activity” has wonderful performances and excellent direction that sell the packaged found footage concept depicting a supernatural occurrence that inevitably ruins a happy couple. “Paranormal Activity” has become a slightly controversial independent film

NaCl Effects on Peroxidase Activity My experiment was to see if adding NaCl to solution would have any effects on peroxidase activity. The materials that were used in this experiment were pH 7 buffer(DI water)‚ peroxidase‚ NaCl‚ guaiacol and hydrogen peroxide; added in that order. Blanks were created for each NaCl concentration‚ 0%‚ 5%‚ 7.5% and 10%. Each cuvette had .5ml of pH 7 buffer‚ 1ml of peroxidase‚ .02ml guaiacol for the experimental cuvettes and 0ml of guaiacol for the blank cuvettes‚

Although researchers agree that extracurricular activities do‚ in fact‚ influence academic performance‚ the specific effect that various activities produce is debated. One study‚ conducted by the National Educational Longitudinal Study‚ found that “participation in some activities improves achievement‚ while participation in others diminishes achievement” (Broh
