Difusión

The video tutorial explains diffusion in both biological and physical contexts. In biology, diffusion involves small molecules crossing cell membranes. In physics, diffusion refers to the reflection or refraction of radiation, such as light or sound, especially on uneven surfaces that scatter in various directions.
