INTRODUCTION Gas exchange is the movement of respiratory gases across a membrane through diffusion. Diffusion is the process of which the respiratory gases across the gas exchange membrane (oxygen from the environment into the body‚ carbon dioxide from the body to the environment). Using the concentration gradient along the gas exchange surface. For gas exchange to occur these three Features are needed; the gas exchange surface needs to be moist so that the oxygen and carbon dioxide can dissolve

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

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied
