The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
- Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
- Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
- The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
- As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.

Answer:
the couler of the pray. how bright they are
Explanation:
Answer: See below
Explanation:
There should be another answer that can be chosen: the rat’s chemical receptors detect chemicals in the fruit that alert the rat to possible danger. Sensory receptors in the rat's whiskers respond to input about the texture of the fruit, maybe it's slimy or rancid, if if it was another factor such as the environment, it wouldn't have approached the fruit in the first place.
