Caffeine has an effect on your heart rate‚ (this is how fact your hear beats) Caffeine is able to change the way your body and mind works Chocolate is known to have traces of caffeine in it also The aim What is the point this experiment;- My aim in this experiment is to see what effects caffeine is prone to on the heart rate‚ Also to compare someone’s heart rate who has consumed caffeine to someone’s who hasn’t. This should give us a developed

Enzymes are a type of protein. They are catalysts meaning they speed up the rate of the reaction. Enzymes activity depends on the concentration of the substrate‚ temperature and the pH. The more concentrated the substrate is the more reactive the enzyme is. The optimal pH for an enzyme is 7.5 and the optimal temperature for an enzyme is 53 Celsius. Extremes in the temperature and the pH of an enzyme can denature therefore destroy it. The enzyme that is in this experiment is Amylase. Amylase is found

speed up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction

incorporated his own ideas to revolutionize the auto industry and make cars a reality for the average American. “That efficiency of mass production enabled him to reduce the cost of the Model T Touring car from $950 in 1908 to just $290 in 1925 while increasing production during that time from just more than 10‚000 to nearly 2 million cars per year”. (1) This obviously changed America as the average person was able to afford an automobile‚ but also began a dangerous standard in the auto industry of cost

experiment was to find how certain factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction

existence of the “hidden economy” is largely documented in the South‚ where the workforce is “characterized by the highest proportion of irregular workers across all sectors” (Destefanis 9). The second major challenge for Italy is the lower productivity rate caused by family-run businesses throughout the country. Since 1992‚ the economy “has been growing at a much slower pace than previously in the post-war period” (Destefanis 7). This slow pace staggered the economy’s development and has affected both

World War II had the largest armed forces involved and was the “most traumatizing and frightening” (Arthur‚ 103) war of all time. There were about 72 million deaths worldwide during WWII but only 45400 were Canadians (Neary‚ Peter‚ 137). With all the death and violence that occurred during World War II there were a few promising things as well. World War II positively affected the development of Canada because the war created more job opportunities which created more money in the economy‚ Canada
