Introduction: Perfume spreads in a room‚ hands bloat when left in water for too long (shriveling is a common misconception)‚ a tea bag’s contents diffuse through the water. These are all examples of diffusion and osmosis. These phenomena happen everyday and people don’t realize what is actually happening. The purpose of the lab is to see the effects of diffusion and osmosis. In part B‚ the higher the concentration of solute‚ the higher the mass of the solution. Methods and Materials: For part A of the

Introduction Enzymes are catalytic proteins. The purpose of a catalyst is to speed up metabolic reactions by lowering the free energy of activation or activation energy. Activation energy is known as the amount of energy needed to push the reactants over an energy barrier‚ so that the downhill part of the reaction can begin (Campbell 151). In an enzyme catalyzed reaction‚ the enzyme binds to its substrate‚ which is the reactant an enzyme acts on. In the reactions‚ the enzymes are very specific

People Elias Howe and Isaac Singer • Singer’s life was not going well in the beginning • He was penniless • Unsuccessful actor‚ ticket seller‚ carpenter‚ and inventor • By 1860‚ singer grew fabulously wealthy • In 1850‚ he had come upon and quickly improved a sewing machine similar to one patented in 1856 by Elias Howe. • Elias Howe sued Isaac Singer for patent infringement and won in 1854 • Since Singer lost‚ he had to pay Howe patent royalties John Deere • Was

Membrane proteins serves as channels for transport of metabolites‚ some act as enzymes or carriers‚ while some are receptors. Lastly carbohydrate molecules of the membrane are relatively short-chain polysaccharides‚ which has multiple functions‚ for example‚ cell-cell recognition and acting as receptor sites for chemical signals. The plasma membrane is a permeable membrane. An important role of the plasma membrane is to maintain the integrity of the cell‚ holding the cell contents together. Membrane

surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated carbon 1 Piece of pH paper Permanent marker Measuring spoon

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

Chapter 11 Vocabulary Relevancies 1. organic agriculture – The return to farming without pesticides; allows small farmers in core countries to compete with agribusiness. When fair trade laws are applied‚ organic farming in peripheral and semi-peripheral countries can bring wealth into a country by exporting to wealthier nations. 2. primary economic activity – most basic use of the natural environment to sustain human functions. Examples: hunting/gathering‚ farming‚ ranching‚ logging
