3%‚ was diluted using 10 mL of hydrogen peroxide and 20 mL of water. In the second beaker‚ a ¼ dilution of potato extract was made using 2 mL of potato extract and 6 mL of water. The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for exactly 5 seconds. It was next dried on a paper towel for 5 seconds‚ and finally placed at the

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

Seamus Heaney – ‘At a Potato Digging’ • Context • • The poem deals with two different potato harvests. One is the harvest from the present day that goes successfully and which delivers a rich crop. The second potato harvest looks back to the famine of 1845 when the crop failed and many people starved. Whilst the famine is no longer a threat‚ its ongoing fear remains and this can be seen in the use of religious language throughout the poem. For example‚ the bowed heads of the potato pickers suggest the

effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that the mass of the potato will decrease as the salt in the solution

Cost‚ Volume‚ and Profit Formulas Heather Jauregui University of Phoenix of Axia College “The Cost-volume-profit (CVP) analysis is the study of the effects of changes in costs and volume on a company’s profits.” (Kimmel‚ P.‚ Weygandt‚ J.‚ & Kieso‚ D. 2003) The analysis is used to maximize efficiency in a business. In order to be effective the CVP analysis has to make several assumptions. These assumptions are that the costs can be fitted into either fixed or variable categories. The

Project Estimating Techniques Project Estimating Techniques One of the most important factors to the success of a project is how well the project is estimated‚ as well as how overall costs are managed during the execution phase by the project manager. Project costs and estimates are vital to the success of any organization to remain competitive in the market. Cost estimating for organizations rely heavily on resources that can sometimes be difficult to obtain. Forecasting and utilizing
