Experiment 8: Hydrogen Phosphate Buffer Systems Purpose The purpose of the lab was to create a buffer solution and observe the capacity of the phosphate buffer system. Also‚ the experiment was meant to provide experience with the calculations and mathematics involved in creating the buffer solution. Finally‚ the lab was designed to provide an insight and appreciation for the necessity and complexity of buffers in our physiology and in the environment. Procedure No deviations were made from

had two sized potatoes‚ 6g and 10g‚ and placed each in three different dilutions of sucrose at 0.5M‚ 0.1M‚ and 0.05M. We also placed a 6g and 10g potato piece in water to act as a control. Based on the weight percent change over 60 minutes‚ the 6g potato piece had faster water movement than the 10g. This confirms out hypothesis that smaller potato pieces will have a faster rate of water movement. Introduction Osmosis is the diffusion of water across a selectively permeable membrane. Water

In the essay “Chicken Hips” by Catherine Pigott‚ she discussed the pressure of society‚ and how‚ in context‚ they were pressured to think that the only way they could be appreciated was to succumb to society.

While being in Gambia‚ Catherine noticed that the skinnier the American people were‚ the more “the

nvestigation into the Factor of Light and Dark Affecting Woodlice Predictions It was expected that a woodlice would prefer a damp‚ dark‚ but moderately warm surrounding. Normally one would expect to find slaters under logs or concrete slabs in one’s garden. Under these large objects‚ the sun cannot reach directly; therefore it is darker‚ damper and colder than the surroundings. Nevertheless‚ in winter we do not see woodlice crawling around very often‚ and‚ also at night‚ it may

The Irish Potato Famine occurred in Ireland in 1845 to 1849‚ when the potato harvest failed. A disease that destroys the edible parts of potato plants known as Late Blight caused the unsuccessful crop. The Irish Potato Famine was the worst famine to occur in Europe in the 19th century. Almost fifty percent of the Irish population had become dependent on potatoes in their diet‚ but the entire population consumed the crop in large quantities‚ especially the rural and the poor. The Potato was very susceptible
