Final answer:
Diffusion is a process based on the random motion of molecules and is a passive movement from higher to lower concentration areas.
Step-by-step explanation:
The correct answer to the question of whether diffusion is the movement through non-random motion is B) False. Diffusion relies on the random motion of molecules, often described as Brownian motion, where molecules move from regions of higher concentration to regions of lower concentration until they are uniformly distributed.
This process is critical in biological systems, such as the exchange of gases like O₂ and CO₂ in the lungs and mitochondria, and does not require energy input to occur.
