Previous PageTable Of ContentsNext Page The Nigerian economy: Agriculture and the livestock sector For some years Nigeria has been seeking to achieve economic take-off by using her oil resources.1 The 1973�74 fourfold rise in oil prices enabled the Government to launch an ambitious investment programme.2 The principal aim of the Third Development Plan was to diversify the economy‚ which at that time was primarily based on oil and agriculture. Diversification was to be achieved by implementing

Water Concentration in Potato Cells Formal Lab Report Purpose: The purpose of this lab is to determine the concentration of water in potato cells. Method: To complete this task‚ we will first soak our potato cells in different concentrations of sugar solutions. Before we actually soak them‚ we will need to know the initial mass of the potato cores. After soaking‚ we will need to know the mass of the final core. We will use the data we collect to find the percent change in mass of the cores

Baseball‚ hot dogs‚ potato chips‚ and pop. What can be more American than that? The potato chip is the king of salty‚ crunchy snacks. Potato chips originated in New England in 1853 at Moon Lake Lodge in Saratoga Springs‚ New York. The inventor‚ a chef named George Crum‚ was part Native American and part African American and a guide in the Adirondack area. The potato chip was invented when a dinner guest returned his fried potatoes to Chef George Crum because they were not crunchy enough. After returning

I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

that affects the rate of osmosis in a potato: * Time * Temperature * Molar * Sucrose solution * NaCl solution * Concentration of liquid * Age of the potato * Variety of the potato * Potassium‚ K(AQ) Factor Chosen: Different Molar of Sucrose Solution In this investigation I will change the molar of sucrose solution to find the increase or decrease in mass change and also the higher or lower the mass change of the potato chip from its original weight will determine

colour of any fruit indicates a rich source of vitamin A. Iron is the most important mineral available from fruit. Some of the greatest minerals in fruits are right under the skin so the skin should be eaten if possible. Storing Fresh Vegetables -Tuber vegetables should be stored in a cool‚ dark‚ airy place. Most will keep for 4-9 months long is stored in cool areas. -Remove tops of root vegetables before storing in a cool‚ moist place they will keep for several weeks if stored properly. -Store

The Science of the Spud — a History of the Potato Battery Experiment There are hot potatoes‚ french fried potatoes‚ baked potatoes and scalloped potatoes. There are potato chips‚ potato pies and potato soufflés. Last‚ but not least‚ there’s the potato battery. Who on earth invented the electric spud? Why does it work? For that matter‚ why would anyone want to see if a potato could conduct electricity in the first place? Well‚ we may never be able to answer some of the questions this quirky experiment

original 1M solution of Sucrose. This is therefore the only thing that is going to be altered as I am investigating how different percentage of water molecules affects the weight of the the potato thus the rate and direction of osmosis. Dependant Variable The dependant variable will be the mass of the potato as this is the variable I will be measuring. From this I can see the change in mass(g) and so work out the amount of water that has moved and the rate of the osmosis in a set time. This can

Exchange‚ which started mostly after 1492 when Columbus traveled from the Old World to the New World‚ can be defined as the time when various items such as plants‚ technologies and food were carried from the New World to the Old‚ and vice-versa. The potato is a great example of the Columbian Exchange‚ seeing as how it was carried from the New World to the Old World‚ and had a significant impact on Europe‚ as well as other countries from various continents. Potatoes were first known to be grown in the

VII. Conclusion The hypothesis that if a potato is placed in a tube with different sucrose concentrations then the tube with the lowest concentration of sucrose will expand the potato the most because the water will move into the potato to even out the concentration levels of the sucrose/ water ratio inside and outside of the potato was supported by the data. The data shows that the potato submerged in the lowest concentration of the sucrose water solution had the greatest percent change in mass
