An osteocyte, a star-shaped type of bone cell, is the most commonly found cell in mature bone tissue, and can live as long as the organism itself.[1] The adult human body has about 42 billion osteocytes.[2] Osteocytes have an average half life of 25 years, they do not divide, and they are derived from osteoprogenitors, some of which differentiate ...
A: According to the Infoplease website from Pearson Education, the biological importance of osmosis is that it facilitates the distribution of essential nutrients in the body and the excretion of metabolic waste products. Cells have semipermeable membranes, and osmosis makes it possible for liquid solvents to pass through these cell membranes.
Osmosis is the diffusion of water across a selectively permeable membrane. A spontaneous transport of solvent occurs from a dilute solute or salt solution to a concentrated solute or salt solution across a semipermeable membrane which allows the passage of the solvent but impedes passage of the salt solutes.This is very important with cells.ll cells have some amount of dissolved salts,proteins and such, the flow of water across the plasma membrane depends upon the concentraton of water in the liquid that the cells are in. In humans the concentrations are equal inside and outside the cell. Therefore, water will neither enter or exit the cell.
