Effect of temperature on enzyme activity In this experiment… Independent variable: Temperature of the amylase Dependent variable: Enzyme activity which is measured by the time for disappearance of starch Controlled variables: Volume of amylase; volume of starch solution; concentration of amylase; concentration of starch solution Prediction of results i) At low temperature‚ the rate of amylase activity is very low. ii) At optimum (=best) temperature‚ the rate of amylase activity is the highest

the affects teratogens have on prenatal development‚ why the alcohol consumption should be reduced completely‚ and I will define what a teratogen actually is. Teratogen is a word used to describe behaviors‚ environments‚ and bodily conditions that can harm the development process of an organism. The process of prenatal development requires a healthy and strict lifestyle. To think that one would have the desire to live any lifestyle other than a healthy one during the development process is crazy

How social learning and aggression affects children’s behaviour Introduction This report introduces you to a study by Bandura‚ Ross and Ross which aimed at finding out how social learning and aggression as contributed to our understanding of children’s behaviour. We will find out why they had done this research‚ what happened during this experiment and their outcomes. Background: Bandura and colleagues researched how we learn‚ particularly how social learning has framed aspects of behaviour

of all three trials. Heat tends to increase the rate of chemical reactions‚ explained in the article Temperature Effects (Introduction to Enzymes) by Chris Jamison. “Like most chemical reactions‚ the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree rise in temperature will increase the activity of most enzymes by 50 to 100% . Variations in reaction temperature as small as 1 or 2 degrees

conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine is a dark blue color in the presence of starch and turns light yellow in its absence. Bacterial Amylase had an optimal temperature of 55°C‚ meaning that starch was

P.3 Explain the difference between physical and environmental factors involved in the development. People working in construction are being told to minimise environmental impacts when carrying out there work. Many negative impacts can be reduced during the planning stage of a build. Any new build will have a negative impact on home owners and businesses. There will be increased traffic on roads and the towns will be fuller. Once the construction has been completed there may be longer term impacts

How do the economies of scale affect break-even analysis? In the video on leverage‚ leverage is compared to a fulcrum in that you need just the right balance of leverage. That would seem to indicate that there is a point where the leverage is just right and that too little leverage may be just as harmful as too much leverage. Do you think this is true? The book discusses the difference between efficiency and effectiveness. Which one do you think is the most important in business and why? Answers:

Environmental Factors of Marketing This paper will discuss the five environmental factors that influence global and domestic marketing decisions that organizations must make. These five environmental factors are technology‚ demographics‚ government‚ culture and economics. Companies are affected differently by these factors depending on the industry they are in and the size of the organization. I will be using the Washington Plaza Hotel to illustrate how these environmental factors affect the
