This essay and its contents is designed to define and discuss the concept of my position on the following statement: “Human activity‚ especially the burning of fossil fuels. It also answers inquiries of; is it a major contributor to climate change? Do I agree or disagree? From my research and readings‚ I‘ve concluded that‚ the foremost effect that burning fossil fuels has on our environment is the greenhouse effect‚ also known as global warming. Carbon dioxide‚ which is also known as greenhouse

catalase activity performed better at 0⁰C than at 100⁰C. Strangely‚ 50⁰C outperformed 37⁰C. Catalase activity was higher for intermediate temperatures such as 37⁰C and 50⁰C than the extreme temperatures such as 0⁰C and 100⁰C. Overall the rate of reaction peaked at 28⁰C and every other temperature had a lower maximum rate of reaction. DISCUSSION The results do not support the hypothesis that optimum temperature would be at 37⁰C. The results do not reflect the textbook narrative of enzyme activity. Enzymes

Each enzyme has it optimum temperature range at which it functions at an optimum efficiency. In this experiment‚ Rennin might have an optimum temperature of 37 degrees Celsius as it is found in the stomachs of young mammals. As the temperature is increased‚ the rate of reaction (time for milk to curdle) will also increase until the optimum temperature is reached (37 degrees). After reaching this set point‚ the activity of the enzyme will gradually begin to decrease and the rate of reaction will

Over this election in 1828‚ it changed the history of voting in many ways! Over the years it changed from in the 1828 election only white men could vote‚ now everyone American citizen has the opportunity to vote. There was only one main party at the time‚ Andrew Jackson was representing the Democratic party‚ and John Adams was National Republican. Today’s election there is two main parties and that is Republican and Democratic. The election was based on the electoral college vote that had changed

1. Introduction: The Optimum currency areas theory is the seminal contributions developed by Mundell (1961)‚ it attempts to answer a question under which conditions a certain country would like to join a fixed exchange rates system. According to Krugman (2000)‚ if the monetary efficiency gain of one country exceeds its economic stability loss‚ the country will wish to join a monetary union/ a fixed exchange rate system. In this paper‚ the theory of optimum currency areas will be analysed in part

destroying our world indirectly which means we do not just go and kill those entire animals‚ but what has caused their extinction is due to “Climate Change” that is the result of the Natural Causes and Human Activities. We used to look at how natural causes have contributed to climate change‚ but human is now even playing a bigger role in causing climate change. Climate can be defined as the average weather effected by slow features such as oceans‚ precipitations‚ and clouds (Slaght‚ 2009‚ p34-41). Out
