    What causes diffusion?

    • The mitochondria of cells

    • Random motion of molecules

    • Spontaneous generation

    • Semi-permeable membranes

    Correct Answer
    A. Random motion of molecules
    Explanation
    Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This movement occurs due to the random motion of molecules. As molecules constantly move and collide with each other, they spread out and mix with other molecules, resulting in diffusion. The other options, such as the mitochondria of cells, spontaneous generation, and semi-permeable membranes, are not directly related to the process of diffusion.
