What Is Selective Permeability? , Selective permeability is the concept that states the cell membrane does exert some control over what goes into the cell or out of the cell, according to Springfield Technical Community College. Cells allow molecules or compounds into the cell via passive or active transport.Read more≫

What Factors Affect Soil Permeability? , Factors that affect soil permeability include grain size, void ratio, water impurities and the volume of air or organic matter entrapped with the soil. Permeability is approximately proportional to the square of the grain size. Soil quality and permeability may vary greatly from one layer of soil to another.Read more≫

What Is Meant by Selectively Permeable? , Selective permeability is a term used to describe cell membranes.
