AMDG THE RATE OF PHOTOSYNTHESIS The Factor of Carbon Dioxide I. Introduction In this lab‚ the rate of photosynthesis will be measured by manipulating a variable that is needed for the process of photosynthesis. Photosynthesis is the process by which plants use light energy‚ carbon dioxide‚ and water to produce oxygen and glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and

Saliva collected at the beginning of experiment was found to have a pH value of 7(neutral) ‚ as expected since the normal pH of saliva is 6 to 7 (Humphrey and Williamson‚ 2001). When testing the enzymatic action of saliva‚ we observed at the end of the experiment‚ that a yellow-red precipitate formed which indicated that sugars were present. The reason that sugars were found and not starch‚ is because saliva contains an enzyme known as salivary amylase which catalyses the breakdown of starch to

reasons for the changes in divorce rates since the 1960s. Divorce rates have increased rapidly since the 1960s from 27000 in the UK in 1961 to 167000 by 2005. There are many reasons for this increase‚ for example decreased stigma of divorce‚ secularisation‚ more rights for women‚ rising expectations‚ and acts put in place by the government making it easier for a couple to obtain a divorce. Decreased stigma of divorce in society from the 1960s has led to divorce rates increasing‚ because it is no longer

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

Exchange rate movement has been an important subject of macroeconomic analysis and market surveillance. Despite its importance‚ forecasting the exchange rate level has been a challenge for academics and market practitioners since the collapse of the Bretton Woods system. Empirical results from many of the exchange rate forecasting models in the literature have not yielded satisfactory results. This paper is constructed for the purpose of comparing the forecast performance of various competing models

of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds

Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect

Cocoa is produced in South America‚ coffee in Africa and tea is produced in Asia have all been used for a very long time to give us a little rush in order to keep us going. Now caffeine is also used as a flavour enhancer in cola and other soft drinks also it has medicinal uses in aspirin preparations and is found in weight-loss drugs and as a stimulant in normal people in everyday to
