Solution A homogeneous mixture of two or more substances with each substance retaining its own chemical identity. Solute – substance being dissolved. Solvent – liquid water. General Properties of a Solution 1. Contains 2 or more components. 2. Has variable composition. 3. Properties change as the ratio of solute to solvent is changed. 4. Dissolved solutes are present as individual particles. 5. Solutes remain uniformly distributed and will not settle out with time. 6. Solute

The cell membrane regulates and controls what kind of molecules ______ move in & out of the cell. 2. When molecules spread from an area of high to low concentration‚ it is called _Diffusion_____. 3. As molecules diffuse‚ they create a _concentration gradient_____
Premium Concentration Osmosis Solution
Introduction Osmosis is the movement of water from a region of higher concentration ( hypertonic ) to a region of lower concentration ( hypotonic solution ) through a cell membrane or other semi-permeable membrane until an equilibrium is reached. It is a special case of diffusion called “ passive transport “ which means no energy is required. Diffusion is the movement of a substance by which the molecules move from a region of higher concentration to a region of lower concentration. Aim

What is the main difference between simple diffusion and facilitated diffusion? Simple diffusion moves molecules from an area of higher concentration to an area of lower concentration without an input of energy. Facilitated Diffusion

that when placed in a hypertonic solution‚ a potato core will have positive water potential in respect to its environment‚ meaning the direction of osmosis will be from the potato to the solution. II. Materials & Methods a. Procedure: i. Obtain all necessary materials for the experiment: the assigned sucrose solution for the group (.2M‚ .4M‚ .6M or .8M)‚ an Erlenmeyer flask and corresponding cork‚ one or two skinless potato cores‚ scale to mass potato cores‚ paper towels and

Cell Membrane Transport The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions‚ and the transportation of molecules across cell membranes. It’s also used to understand‚ and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into

Diffusion & Osmosis: Introduction: This experiment was performed to demonstrate the process of osmosis and to show visible as well as quantitative evidence proving that osmosis occurred. Through the tasks of determining the percent concentrations in two different solutions‚ we were studying the process of osmosis. Osmosis is the best way to perform this experiment because as we went through the experiment‚ the weight of the beaker/dialysis tubing changed and the only logical explanation was

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and
