    • 6 Pages

    How is Osmosis Affected By the Concentration PLANNING Independent Variable The independent variable in this experiment is the thing that I will be changing in the experiment. This is the range of concentrations that have been obtained by diluting the original 1M solution of Sucrose. This is therefore the only thing that is going to be altered as I am investigating how different percentage of water molecules affects the weight of the the potato thus the rate and direction of osmosis. Dependant

    Investigate osmosis between potato tissue and sugar solutions. Aim: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato core of a given size 10mm Hypothesis: Osmosis is defined as the net movement of water or any other solutions molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable

    Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature‚ molecular weight‚ and movement. To test the rate of diffusion a drop of dark food coloring was added to a glass of tap water and it was timed to see how long it took for the drop to reach the bottom of the glass. This procedure was repeated three

    icJohn Melvin Mateo BS AT - 1A NSCI 121 Assignment no.1 (Finals) 1.)What is Osmosis? Osmosis is the diffusion of the movement of water from a region of higher concentration to a region of lower concentration through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion (passive transport).  Basic Explanation : Osmosis can occur when there is a partially permeable membrane‚ such

    Why is diffusion of innovation and technology important? When I think of diffusion of innovation and technology‚ I think of evolution or how a product‚ idea or theory goes from a thought in someone’s mind to an actual working process and then through time develops into better products to meet society’s needs and wants. Many times certain societies have a special trait‚ characteristic or ability that enables them to be great at certain types of technology or maybe they produce certain products that
