The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929)

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured
