investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

Two part response to “Men are from Mars‚ Women are from Venus” In an article entitled‚ “Men are from Mars‚ Women Are from Venus‚’’ John Gray explains in what ways men and women differ from each other. He says‚ women complain about men that when they talk to them‚ they do not pay an attention. Men complain about women that they try to change them all the time.

American leadership and supporter of the Bush policy‚ in the analysis of the disagreement between United States and Europe goes so far that he demonstrate these differences as planetary diversity‚ because‚ apparently‚ Americans are from Mars‚ and Europeans are from Venus. This characterization reflects a greater tendency of American use of force and war‚ while Europeans are recognized by pleasure and hedonism‚ and this characterization can be taken as a witty prologue to the differences that have

An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job
