The Assam Power Distribution Company Limited (APDCL) has been forced to resort to frequent and prolonged power cuts due to the shortage of power generation‚ they said. The situation was likely to improve within a couple of days as work was on to restore the transmission towers. However‚ the gap between the demand and supply of power would continue to exist till

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

Seamus Heaney – ‘At a Potato Digging’ • Context • • The poem deals with two different potato harvests. One is the harvest from the present day that goes successfully and which delivers a rich crop. The second potato harvest looks back to the famine of 1845 when the crop failed and many people starved. Whilst the famine is no longer a threat‚ its ongoing fear remains and this can be seen in the use of religious language throughout the poem. For example‚ the bowed heads of the potato pickers suggest the

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

is the solution with the lower salt concentration. My hypothesis is that the potato core will increase in size. When the solution is hypertonic‚ the potato will decrease in size making the potato hypotonic. Osmosis is really interesting‚ that is why I chose to write this report about it. Materials and Methods We first cut out six cores out of a potato. We trimmed them all to the same length using a razor. After we had cut them to the same size we weighed them using a scale. The weight ranged from

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
