Osmosis, or the movement of water into and out of a cell, is directly related to the concentration gradient on both sides of the cell membrane and indirectly to the fact that

Indirectly to the fact that it does not need energy to transport water from a concentration gradient.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave
