Adhesion is the attraction between molecules of different substances, while cohesion is the attraction between molecules of the same substance.

Adhesion is important in many biological processes, such as the ability of water to be absorbed by plant roots or the ability of blood to flow through blood vessels. Cohesion is also important in biological systems, such as the ability of water molecules to stick together and form droplets.

Both adhesion and cohesion play a role in the phenomenon of surface tension, which is the tendency of a liquid surface to minimize its surface area. This is why water droplets form spherical shapes and why insects can walk on water without sinking.

Overall, adhesion and cohesion are fundamental forces that help determine the behavior of liquids and solids in various natural and artificial systems.

Correct.
