distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling point of 110 degrees Celsius. Gas chromatography was

This report will cover the adaptations relating to gas exchange in insects‚ fish and mammals. These all have different gas exchange systems but work in similar ways. All the animals studied have the same characteristics in order for them to be able to work properly. Overview The gas exchange system is the process in which oxygen enters the cells of many living animals. Some factors that affect how efficient a gas exchange system is are things such as the distance that the molecules have to go before

fuel is a natural fuel‚ such as coal or gas‚ formed in the geological past from the remains of living organisms. Humans use fossil fuels every minute of each day in order to survive. Coal‚ oil‚ petrol gas‚ diesel fuel‚ and natural gas are all used from fossil fuels. That being said‚ we use it with some things such as‚ central heating and air conditioning‚ driving a car‚ shopping for groceries that were delivered by a truck or train‚ and/or using an outdoor gas grill for cooking.

Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning
