Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

clock * multi meter Procedure 1. Cut the potato in half and place them next to each other‚ flat face down on a plate 2. Connect one end of the white wire to one of the nails and then place the nail into one half of the potato. 3. Connect the other end of the white wire to the battery holder inside the digital clock. 4. Connect one of the pennies to one end of the black wire then put the penny into the same half of the potato as the nail with the connected to it. 5. Connect

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate

The main purpose of the economic stimulus package was to prevent the re-emergence of the panic that gripped investors in 2008. It also aimed to restore trust in the finance industry by further limiting bonuses for senior executives for companies that received TARP funds (Recovery.gov).

Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

“A Chip of Ruby Glass” Thesis Essay Take a moment‚ imagine your life without learning opportunities‚ knowing no matter how hard you try‚ your life will still end up being a shoe-shiner‚ or maybe worse. Once you finished‚ take a look at history‚ see what the life of the black was like and relate to them. Many have died‚ sacrifice their life for the banishment of racism‚ and so did the people who agrees with it; the oppression they were under was unbelievable‚ it drove thousands crazy and finally

in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement of water into the potato pieces. Therefore

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

results. Pros A pro would be that Frito-Lay knows where the majority of their sales are happening. Due to about 90 percent of them being in supermarkets and convenience stores. It is also a pro that they have determined what percentage of each size package and flavor they are selling. In addition they have also determined the percentage of cannibalization that will happen. Another pro is that the cumulative repeat percentage steadily rose every week. Cons A con to these test market results would
