Mayonnaise is a heterogeneous mix. The correct answer is colloids.
<span>B. Osmosis is movement of proteins, and diffusion is movement of water.

D. More collisions occur and the time required for the reaction decreases
This happens because according to collision theory, when energy (in this case, thermal energy) is applied to particles, they move/vibrate more quickly.
