easy · Enhanced ACT science
A biologist is testing the 'Diffusion Rule' by placing a drop of blue dye into a beaker of clear water. After one hour, the water is a uniform light blue.
What happened to the dye molecules?
- They were pumped across the water molecules using ATP energy from the beaker.
- They moved from an area of high concentration to an area of low concentration.
- They underwent osmosis to balance the water pressure inside the dye droplets.
- They changed their chemical formula to match the frozen state of the water.
