experiment to find the optimum temperature and pH for starch on amylase. The experiment was carried out in one day. The researcher and a partner did the experiment based on a lab manuel from class. Data was collected from the experiment and to be displayed on graphs. Then the optimum pH and temperatures were to be calculated based on the findings. The hypothesis was disproved due to the optimum pH of 5 but the other findings supported the hypothesis of the optimal temperature being 45 degrees Celsius.

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

The effect of Temperature on the Xylem of Tomato Plants Question: How does temperature affect the Xylem in Tomato Plants? Introduction: Throughout this experiment I will be testing the size of the Xylem in Roma tomato plants when exposed to different temperatures. I will be placing six Roma Tomatoes in six different area which will each be in different temperatures. After three weeks of constantly watering the tomato plants with blue dyed water I will cut the plant from the root and examine

As a check on your assumptions‚ be sure that the elements in series have the same current and that the elements in parallel have the same voltage. Restrict your decisions to single elements‚ not combinations of elements. (a)R1‚ R2‚ and E are in series; R3‚ R4‚ and R5 are parallel. (b)E and R1 are in series; R2‚ R3‚ and R4 are parallel.

Effect of Temperature on Content of Vitamin C Introduction A daily intake of Vitamin C is essential for humans. Without it‚ the disease scurvy develops as sailors‚ explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C is found in high levels in foods such as oranges‚ limes‚ lemons‚ blackcurrants‚ parsley and capsicums. Vitamin C is water

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

"Integrity without knowledge is weak and useless‚ and knowledge without integrity is dangerous and dreadful"‚ quoted Samuel Johnson. Integrity in the eyes of a teenager means not cheating in class‚ obeying and respecting school rules‚ and finishing and completing anything assigned in school. When in class‚ teenagers have plenty of opportunities to cheat during tests‚ quizzes and other assignments. Integrity means not taking advantage of these opportunities and being honest towards yourself and
