Question

The distribution of particles across space from high concentration to low concentration

Answer 1

Answer:

This question is asking to state what is being defined. The term defined in the question is called DIFFUSION

Explanation:

Diffusion is the movement of particles/fluids from a region where they are highly concentrated to the region where they are less in concentration across a space. Diffusion is a form of passive transport i.e does not require energy input to occur. This is because the movement occurs down a concentration gradient.

A concentration gradient i.e difference in concentration occurs when there is an uneven amount/concentration of particles in two regions. Hence, movement occurs naturally to the direction where the particles are less concentrated from where they are more concentrated.
