Potato Cell Cytoplasm Composition PURPOSE: To determine the concentration of salt in the cytoplasm of potato cells HYPOTHESIS: Increase in salt concentration results in a hypotonic solution where the mass of the potato increases due to the movement of water into the cell. On the other hand‚ decrease in salt concentration results in a hypertonic solution where the mass of the potato decreases due to the movement of water outside the cell. MATERIALS: Potato Forceps Stopwatch Scalpel Test

Keegan Bauman Potato Lab Dr. Peano Block 1 Introduction: Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis‚ which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt‚ water and iodine solution. The dependent variable is the mass of the potato after being

Irish literature Early and medieval literature The earliest Irish literature consisted of original lyric poetry and versions of ancient prose tales. The earliest poetry‚ composed in the 6th century‚ illustrates a vivid religious faith or describe the world of nature‚ and was sometimes written in the margins of illuminated manuscripts.

Irish Immigration to Canada The Irish began immigrating to North America in the 1820s‚ when the lack of jobs and poverty forced them to seek better opportunities elsewhere after the end of the major European wars. When the Europeans could finally stop depending on the Irish for food during war‚ the investment in Irish agricultural products reduced and the boom was over. After an economic boom‚ there comes a bust and unemployment was the result. Two-thirds of the people of Ireland depended

the fields and harvest the crops‚ creating another chain reaction but with a positive spiral. This is an example of how food distribution plays a major role on famine and also how stable governments affect the food distribution in Africa. Most studies on the famine epidemic throughout Africa state that HIV/AIDS plays a major role in famine; this can be attributed to lack of health care in the continent which can be established if governments were established. Stable governments may also play a role

Famine Famine can be defined as a temporary failure of food production or distribution systems in a particular region that leads to increased mortality due to starvation and diseases that result from lack of food. Famine is a very serious crisis that must be solved because famine leads to many hunger-related deaths worldwide. “In 1996 about 849 million people lived in famine‚ about 35‚000 people die each day. A majority were children”. (Clark 148)

The purpose of this was to decimate any potential threats and opposition to his rule. Not only did he target members of the communist
