AP Bio Lab Report Osmosis and Diffusion Introduction When a substance is released into an area‚ the random movement of its molecules results in a multitude of collisions. These collisions‚ in turn‚ lead to a dispersion of the molecules. The overall movement of the molecules will be from an area of high concentration‚ where there will be more collisions‚ to areas of low concentration‚ where the number of collisions will be much less. This process of dispersion will continue until there is no

which causes continuous upward movement of water and mineral salts and this force is called transpiration pull. Apart from to water‚ gas like carbon dioxides from the air can also pass through by the pore of the surface of the plants for photosynthesis. But in this experiment‚ we would like to focus on the negative pressure which can pull the water up through the xylem but not the CO2. Principle: The Cohesion-Tension Theory is one of the force which cause the movement of water and hence the transpiration

culture vials for the flies were created. After wearing the proper safety gear‚ including but not limited to gloves and a lab coat‚ the fly food source was made using roughly an equal amount of distilled water and fly food. These were mixed until it had a mashed potato-like consistency. It mustn’t be too liquid-like as it will kill the flies; and should be solid enough to not slide around the vial. After obtaining and labelling a new vial‚ the food mash was placed inside‚ filling about one inch of the

The Thickness of Aluminum Foil Lab In the study of Chemistry‚ we encounter very large and very small numbers. For example‚ the size of a molecule or thin layer of molecules is very‚ very small and difficult to measure directly. In order to “measure” such numbers‚ we often use one measured quantity and another known property to calculate the unknown value. In this experiment‚ we will use this approach to calculate the thickness of various types of aluminum foil‚ a quantity whose direct experimental
