concentration of the reactants and products does not change with time. Before this experiment‚ we were educated on how osmosis functions. Osmosis is a process which molecules and water take to usually get through a selectively permeable membrane in order to reach equilibrium. It is a passive transport which requires no ATF and water moves from high to low water concentration. When osmosis is completed‚ there should be an equal concentration o water on both sides of the experiment. We have also learned

The Sociological Investigation ~ These notes are taken and adapted from Macionis‚ John J. (2012). Sociology (14th Edition). Boston: Pearson Education Inc. There are two basic requirements for sociological investigation: 1. Know how to apply the sociological perspective or paradigms or what C. Wright Mills termed as the “sociological imagination.” 2. Be curious and ready to ask questions about the world around you. There are three ways to do Sociology. These three ways are considered as

Introduction Diffusion and osmosis are two types of passive transport. Diffusion is a random movement of molecules from an area of high concentration to an area of low concentration. Osmosis is a type of diffusion that diffuses water through a selectively permeable membrane. There were two parts to the experiment‚ the dialysis tubing lab and the potato lab. In the first experiment‚ the dialysis tubing acted as a semi-permeable membrane. A semi-permeable membrane is a membrane

I was astonished when I heard the news‚ I received Thursday afternoon from my manager! Pop Chips asked me to be in an ad for them! If you have never heard of Pop Chips‚ they are all-natural Potato Chips and are fantastic. As we make our way to the photoshoot‚ I had this weird feeling in my stomach. I think it was just the rush of excitement and nervousness getting to me. When we arrived‚ I was pulled straight out of my car and escorted to my dressing room‚ so we could get started ASAP. It took a

Science Coursework Trypsin Investigation Aim I am going to prove that temperature effects the rate in which the enzyme Trypsin breaks down milk substrate into amino acids. Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

Diffusion and Osmosis Diffusion -the process by which molecules spread from areas of high concentratiion‚ to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM DIFFUSION Concentration gradient - a difference between concentrations in a space. Molecules will always move down the concentration gradient‚ toward areas of lesser concentration. Think of food coloring that spreads out in a glass of water‚ or air freshener sprayed in a room

the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚ hypertonic‚ or hypotonic

to a greater number of species present. In this investigation‚ I am going to take the role of an ecologist to survey two different areas of two different grasslands (pasture and park grassland) and estimate the biodiversity. I will be doing this investigation in a group of four students and we will be using taking samples in a quadrat and then measure the soil temperature‚ soil pH and moisture in those quadrats. Hypothesis: In this investigation‚ I expect the species richness of the pastures

exterior and regulate the movement of substances in and out of the cell. Diffusion is how substances more in and out of the cell. There are several types of diffusion‚ but for the purposes of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the
