How does pH affect the activity of the Amylase? Abstract: In my experiment I aimed to observe how ranging pH levels will affect the rate in which amylase will break down the starch molecules. I will be measuring the time it takes for the dark liquid to disappear and leave a yellow brown liquid to be shown‚ which would show that there is no starch present in the solution because it would have broken into maltose by adding amylase. Results did not fully demonstrate what we expected in our hypothesis

Pollution is the induction of harmful material or by-products discharged into the earth ’s environment. Pollution is one of the foremost problems in America and the world today. Pollution damages the environment and human health. Pollution has caused a multitude of problems ranging from healthcare issues like lung cancer to the current problem of the green house effect. Pollution is everywhere and humankind persists on living with this problem. What rational is behind this faulty persistence?Automobiles

Biology Lab Report Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic

Water Pollution and Its Effects on the Environment Water is probably the most important resource we as people have. Humans can survive without food for several weeks‚ but without water we would die in less than a week. On a slightly less dramatic note‚ millions of liters of water are needed every day worldwide for washing‚ irrigating crops‚ and cooling industrial processes‚ not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water‚ we use

The Effect of The Construction of The Reservoir to the Environment A very good morning to our lecturer‚ Mr. Koh‚ and all my fellow friend. Nowadays‚ the number of the construction of reservoir is keep increase which the total of the flooding area of the reservoir now is up to 400‚000 〖km〗^2. The reasons for the construction of the reservoir had been related to the needs of the consuming of water by the all the people in the world nowadays. The water is used for many reasons such as for drinking

Modern Agriculture: Its Effects on the Environment Agriculture has been a major component of the United States economy ever since colonial days‚ when 9 out of 10 working persons were employed on a farm. Produclivity of American agriculture has tripled since then‚ and today only 3 percent of our labor force produces enough food and fiber to meet domestic needs as well as supplying about 10 percent of total overseas consumption. This huge increase in efficiency has been the result of many factors

allowing China to become the world’s largest exporter of technology goods and largest manufacturer in the world. This rapid economic growth did have negative effects on China’s environment‚ as growing Chinese industry resulted in a higher need for energy use. This high energy consumption from the reform years resulted in China’s environment becoming deteriorated. The rapid economic growth has resulted in China’s being on ‘the cusp of environmental catastrophe’ as 300 million people have no access
