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

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

This was conducted through four different experiments. The first tested the effect of temperature on enzyme activity. The independent variable in the first experiment was the temperature of the solution of pH 7 buffer‚ potato juice‚ and the enzyme. The independent variable for the second experiment was the pH of the phosphate buffer. The independent variable for the third experiment was the enzyme concentration of the solution‚ and finally the independent variable of the

The Hidden Power Behind The Comics Strips The comics strips are a sequence of drawings which arranged in related panels. They usually come in series and used to display brief humor or form a narrative. Also‚ they may come as only pictures or they may include some text. Let’s take " Calvin and Hobbes " as an example. “Calvin and Hobbes” is a comic strip about an imaginary world of Calvin‚ who is just a six years old boy‚ with his trusty stuffed tiger named Hobbes. Hobbes is alive only

variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are the amount of water‚ amount of salt‚ and the size of the potato. If the potato is placed in a higher salt concentration‚ then the potato will decrease its size. We started the lab by cutting the potato core length (44

Comic strips (cartoon strips) are drawings‚ or a collection of multiple drawings‚ which tell a story; they are often combined with words to help tell the story‚ or give the punchline. This form of story telling (through imagery) has existed since Ancient Egyptian times‚ as well as textiles from medieval Europe. The Paupers Bible is a tradition of picture bibles beginning in the later Middle Ages‚ which depicts biblical events with words spoken by the characters written in scrolls (Appendix A). This
