dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first dissolve into a fluid before it can diffuse into a cell. Having a moist gas exchange surface ensures the gases can be dissolved. Thirdly‚ the membrane through which gases diffuse must be thin. Gas exchange is driven

Just below the surface The story is written by Kate Nivison and takes place in a London suburb in an upper class environment (p. 41‚ l. 14) in modern time (p. 42‚ l. 23). It is a first person narrator so we sympathize with Indrani. Indrani: * Is an Indian woman (p. 42‚ l. 37) * Is education‚ but not highly educated * She is very bigoted (p. 42‚ p. 29-30) * She thinks the British people are xenophobic (the woman in the shop and the men from the council‚ p. 43‚ l. 15) *

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental

Traffic Volume Studies Traffic Volume Studies • Engineers often use counts of number of vehicles or pedestrians passing a point‚ entering an intersection‚ or using a particular facility such as travel lane‚ crosswalk or sidewalk. Counts are usually samples of actual volumes‚ although continuous counting is also sometimes performed. Manual Observation Typical equipment needed for manual counts are: Tally Sheets‚ or • Mechanical Count Boards‚ or • Sampling periods may range from

potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying more kinetic energy the chance

Current Ratio: The current ratio gauges how capable a business is in paying current liabilities by using current assets only. Current ratio is also called the working capital ratio. A general rule of thumb for the current ratio is 2 to 1. However‚ an industry average may be a better standard than this rule of thumb. So‚ according to the information that we got‚ in 2007 Beximco Pharmaceutical’s current ratio was 1.80 which declined to 1.10 in 2008 and ultimately in 2009 it boosted up to 2.97‚ that
