The two variables that affect the rate of diffusion are: A. The size of the molecule. The larger molecule will diffuse more slowly than the smaller molecule. B. The nature of plasma membrane. If the membrane is composed of lipid portion.‚ only lipid soluble molecules can pass through while water molecules

Civilizations began and of course empires grew. Several reasons lead to the evolution of large‚ powerful empires. Some include cultural diffusion‚ great leaders‚ inventions‚ and more. The main reasons were independent inventions and cultural diffusion. The best explanation for the evolution of the large powerful empires was cultural diffusion. Cultural diffusion is when a culture spreads from one group or empire to another and therefore the empires cultures are diverse and the more the diverse a

Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water is equal on both sides.

Band broadening theory (Van Deemter equation) It is well recognized now that column band broadening originates from three main sources: 1. multiple path of an analyte through the column packing; 2. molecular diffusion; 3. effect of mass transfer between phases. In 1956 J.J. Van Deemter introduced the equation which combined all three sources and represented them as the dependence of the theoretical plate height (HETP) on the mobile phase linear velocity. Originally‚ it was introduced for gas

Cell Membrane Simple diffusion is when a small‚ non-polar molecule passes through a lipid bilayer. It is classified as a means of passive transport. In simple diffusion‚ a hydrophobic molecule can move into the hydrophobic region of the membrane without getting rejected. Simple diffusion does not involve a protein. An example of simple diffusion is osmosis. Hydrophilic molecules cannot participate in simple diffusion because they would move into the hydrophobic region of the membrane and be
