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

your car battery like a pro One of the simplest things you can do with your r car is changing the battery. There are several indicators to warn you that you should replace the vehicle battery. Although battery manufacturers will always claim the product will last for more than five years‚ normal car batteries will last for only two years. To evade problems with the car‚ it is advisable to change car after two and a half years. Some of these signs include: Indicators that the car battery needs to

Batteries contain heavy metal such as mercury‚ cadmium and nickel which can contaminate the environment when batteries are improperly disposed of. When flamed‚ certain metals might be release to the air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before

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

be discussing a potato chip company that has changed its market structure and what affects this change has made on the company‚ businesses that work with the company‚ and consumers. Prior to Wonks potato chips being in existence it was independent potato chip companies that operated in the Northwest that were ran in a competitive structure and in long-run competitive equilibrium. Once these potato chip companies were all bought up and turned into one company called Wonks potato chips which is now

Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

In the early 1800s life in Ireland wasn’t easy‚ Irish citizens got by day to day by farming and relying on the potato. The potato was their main source of food and money. With out the potato the Irish would have nothing. No one was prepared for what was about to happen in 1845‚ the beginning of the Great Irish Potato Famine. The Irish Potato Famine was the worst tragedy in the history of Ireland. The outcome of the famine would result in hundreds of thousands dead‚ an failure of the economy
