Biology Lab Report Investigating Alcoholic Fermentation and the Affects of Yeast on Dough Aim: The aim was simply to investigate whether or not yeast had any affect on causing dough to rise when baked and to experiment with alcoholic fermentation eg. to see if it gave off carbon dioxide. Introduction: Following a few weeks of fermentation theory‚ groups of three to four were assigned and told to conduct a series of experiments involving the affects of fermentation. My group consisted of

Definitions Community psychology is that branch of psychology concerned with how people relate to community and society‚ and according to this approach there are multiple levels in which individuals connect to the community and this includes friends or family‚ workplace‚ religion‚ culture and society (as cited in Community Psychology Linking Individuals and Community‚ 2001).Psychologists working in this arena use collaborative

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

THE EFFECT OF INHIBITORS AND MANIPULATION IN ENERGY PRODUCTION OF YEAST CELLS FOR GLYCOLYSIS AND FERMENTATION INTRODUCTION The aim of this experiment was to study the process of alcoholic fermentation in Saccharomyces cerevisiae (yeast cells) and measure the rate of Co2 production during anaerobic breakdown of the respiratory substrate‚ sucrose‚ in the yeast cells. The effects of an inhibitor on respiratory enzyme were also looked at. It is hypothesized that the five different reaction mixtures

I expect that the more concentrated the enzyme the faster the reaction time will be. Changing the concentration of the enzyme will affect the rate of the

Do you agree with the view that the main cause of the Pilgrimage of Grace was a widespread dislike of religious changes? There were three main rebellions in Henry VIII’s reign as king; The Lincolnshire Rising‚ The Pilgrimage of Grace and Cumberland Rebellion. These rebellions were all connected because each one triggered off the next one. The three main factors that set off the rebellions were the economic state of the country‚ the political state and the religious activities at the time. There
