Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water

Four Products Case Question 1. Which of the four products are you most optimistic about in terms of likely success? Why? Answer: I really like two ideas presented in the case: Stave Jigsaw Puzzle and Polytrack. Both are dealing with big money and luxury; while one is aimed to please‚ impress and entertain real “big wallets” owners‚ the other seems to be a real innovative breakthrough in equestrian sport. Stave Puzzle attracts me with a perfect match of the target market – rich fine people who

B. Yeats‚ 1921 TEACHER ’S INTRODUCTION Between 1845 and 1850‚ more than a million Irish people starved to death while massive quantities of food were being exported from their country. A half million were evicted from their homes during the potato blight‚ and a million and a half emigrated to America‚ Britain and Australia‚ often on-board rotting‚ overcrowded "coffin ships". This is the story of how that immense tragedy came to pass. The necessary historical and political context for a

change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows this ion through‚ the ions will move from

If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH
