The process of diffusion does not require any energy because the particles move towards equilibrium (option B).
<h3>What is diffusion?</h3>
Diffusion is the movement of fluids (gases) from a region of high concentration toward regions of lower concentration.
Diffusion is termed a passive transport because it does not require energy to occur.
Diffusion as a transport mechanism does not require energy in form of ATP because it moves molecules towards/down a concentration gradient.
Therefore, the process of diffusion does not require any energy because the particles move towards equilibrium.

Answer:
Experiments provide evidence.
Explanation:
You do experiments to answer a question (ex. can plants survive without water?). You answer your experiment's driving question with evidence (ex. no, plants can't survive without water because the plants in our experiment died without water, while the ones that received water grew).
I hope this helped!
