There are concentration gradients in such areas that affect particles motion strongly.

Diffusion is the movement of molecules due to a concentration gradient.

A concentration gradient is established between the root and the soil water.

According to the theory, sometimes water is absorbed against concentration gradient.

These are absorbed by the root hairs against a concentration gradient.

They have a rich blood supply to keep a concentration gradient.

This concentration gradient is created by molecules which cannot pass through the membrane.

These forms of transport require energy, as the products being transported are usually moving against a higher concentration gradient.

Building a concentration gradient of non-volatile components at the surface is another.

Due to a concentration gradient of the ions, mass transport must take place.

The temperature gradient alone causes a density gradient that decreases with depth.

Perturbations caused by density gradients and winds will be backed out from these measurements.

As neurogenesis occurs, a density gradient of neuronal cells appears in the body.

Such a density gradient may be continuous or prepared in a stepped manner.

The term refers to the movement of water over large distances as a consequence of global oceanic density gradients.

The blood was separated by density gradient, which left a population of cells enriched in lymphocytes and monocytes.

The caesium chloride molecules sink to the bottom of the test tubes creating a density gradient.

"Yes, due to the refraction effect from the density gradient of the thick atmosphere," Percy said.

The role of the density gradient depends on its sign.

As a general rule, establishing density gradients between miscible substances is very tricky, because they are inherently unstable.
