Diffusion across a Selectively Permeable membrane Introduction: Diffusion is movement of molecules from one area of concentration to another. This process is vital for the life functions of cells. Cells have selectively permeable membranes that allow only certain solutions to pass through them. Osmosis is a special kind of diffusion that allows water to go through semi-permeable membranes of high water potential to a region of lower water potential. Water potential measures the tendency of water to

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no

Lung Volume Activity The graph below is called a spirograph. It represents the amount of air that moves into and out of the lungs with each breath‚ as measured by a device called a spirometer. (The terms that are used to describe the features of a spirograph are explained below.) • Tidal volume is the volume of air that is inhaled and exhaled in a normal breathing movement when the body is at rest. • Inspiratory reserve volume is the additional volume of air that can be taken into the lungs

There are three main nerves in your hand radial nerve‚ median nerve‚ and ulnar nerve. Each one of these gives movement and feeling to different areas of the hand. The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand. The most common place for this nerve is behind the inside part of the elbow. The radial nerve descends down the arm with in the triceps with in the upper arm. Then moves down the arm within the humerus also known as the radial

The plasma membrane is a fluid phospholipid bilayer. The outside of the bilayer is hydrophilic portions of porteins and phospholipids because they are exposed to water. This results in a stable membrane structure. Inside the bilayer hydrophobic portions of proteins and phospholipids because the inside of the bilayer is nonaqueous. the proteins bob in the fluid bilayer of phospholipids. The proteins also vary in structure and function. There are teh integral proteins; transmembrane
