The Stanford prison and BBC prison Experiments comparison In summary the studies showed that the behavior of the ‘normal’ students who had been randomly allocated to each condition‚ was affected by the role they had been assigned‚ to the extent that they seemed to believe in their allocated positions. The studies therefore reject the dispositional hypothesis. The Stanford Prison Experiment demonstrates the powerful role that the situation can play in human behavior. Because the guards were placed

PLANNING COURSEWORK- STARCH AND AMYLASE AIM The aim of this coursework is to investigate the effect of temperature change‚ on the rate of hydrolysis of starch catalysed by amylase. PREDICTION I think that as the temperature increases‚ the rate of reaction also increases‚ to a point when it dramatically decreases. On graph 1‚ you will see a sketch of the graph which I expect to be the result of the experiment. SCIENCE REASONING I think my prediction is correct because the rate of

reaction by converting a specific reactants into a specific product. The enzyme activity will also be affected by temperature and pH value. In this experiment‚ enzyme was placed in carbohydrate solution at different temperature to identify unknown carbohydrate solution. The enzyme that involved in the reaction is salivary amylase. The action of amylase on starch is with the mixture of IKI (iodine and potassium iodide test).Starch solution will have a blue-black colour in the mixture but no changes

What amount of amylase is the best to produce a better reaction with starch? A 1% solution of amylase‚ made from 0.15g of amylase added to 15ml of water‚ a 2% solution of amylase made of 0.3g of amylase added to 15ml of water‚ and a 0.5% solution of amylase made of 0.75g of amylase to 15ml of water were created. A 0.25% starch solution was also created‚ and 3ml was added to each of the 4 test tubes. 1 drop of iodine was added to each test tube. 4ml of the 1% solution was added to the first test

The Milgram experiment‚ as it is now called‚ was considered a turning point in social psychology and the science of obedience. In a new study from Poland‚ a group of researchers wanted to see if the premise held up. That is‚ 50 years later‚ would people still respond to an authority figure in the same way as they did in Milgram’s original experiment? "Upon learning about Milgram’s experiments‚ a vast majority of people claim that ’I would never behave in such a manner‚’" study co-author Tomasz

Temperature Affects Amylase Activity Abstract This study of the effect of temperature on the enzyme amylase was performed to determine the relationship between the enzyme amylase and temperature. The rate of reaction was found to increase as the temperature of the environment was raised. As the temperature was raised from 5°C‚ 20°C‚ 35°C and finally to 80°C the rate of reaction followed this trend and also increased. However as predicted in the hypothesis of this experiment when the temperature

Enzymatic Activity of Salivary Amylase Abstract: Salivary amylase is an enzyme that can digest starch molecules and break them down to sugar molecules. In this experiment‚ the enzymatic activity and specificity of salivary amylase was examined depending on the changes in pH and temperature. In the first part of the experiment‚ the effect of temperature was determined‚ using constant temperature bath (4‚ room temp‚ 37‚ 50‚ 60‚ and 70°C). Having the room temp and 50°C as the highest and 37°C as infinite

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

In "Dr. Heidegger’s Experiment‚" by Nathaniel Hawthorne‚ the magic book and dust are symbols that help illustrate Hawthorn’s theme of how people should lock their past away and always work for the future. When the four guests drink the fountain of youth Dr. Heidegger is experimenting whether people have learned anything from their earlier years in life. Overall the reality of life will emerge and the choice of resisting or going with the flow will surface. One symbol is the magic book‚ which is
