What two properties of water contribute to capillary action?

Answers

Answer:

Adhesion and cohesion

Explanation:

Capillary action refers to the ability of water to move in small-diameter or narrow tubes against the force of gravity. Water has a tendency to form hydrogen bonds with other water molecules.

Intermolecular hydrogen bonding allows the water molecules to stick together. This tendency of water molecules to stick together is called cohesion. Adhesion is the ability of the water to stick to other substances with polar or charged groups. As a consequence of cohesive and adhesive properties, water exhibits capillary action. When water moves through microscopic spaces present between the soil particles towards the roots, it is capillary action.

How can an injury to a peripheral nerve cause loss of both sensory and motor functions?

Answers

The reason is that peripheral nerves have both sensory and motor fibers. 

Through these sensory fibers, peripheral nerves receive signal and send them to the brain. Also, through motor fibers, peripheral nerves send information to the muscles. When a peripheral nerve is damaged, the both functions will be lost.

What is the benefit of using a shortcut in a reaction between two chemicals

Answers

The benefit of using a shortcut in a reaction between two chemicals is that sings of a chemical change will still be found. We will still get a new substance and its chemical and physical properties will differ from those of the original substance.


I hope it helps, Regards.

A reaction with a shortcut would yield more chemical output.
