marine worm.

Please help me with this question. I would like a real answer and not a link to anything if possible. If there is a link, I will not use it and report it.
Thank you.

Diffusion is rapid for short distances but slow for long distances

Explanation:

Let's call t the time required for molecules in a solution to move from a to b, and d the distance between a and b. For what the sentence says

t ∝ √d where ∝ means proportional.

So, as the distance increases, the time of diffusion increases too, and the process is slow. So, diffusion is rapid for short distances but slow for long distances.
