Critically discuss the transport mechanisms across the membrane​

Diffusion, osmosis and active transport.

Explanation:

. Diffusion is the movement of substances from a region of high concentration to a region of low concentration across the membrane.

.Osmosis is the movement of water molecules from a hypotonic solution to a hypertonic solution across the membrane.

.Active transport is the movement of substances from a region of low concentration to a region of high concentration across the membrane with the utilization of energy.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
