There is no pigment in the brain, so it is in it's natural colour, grey.
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.

Movement and balance are monitored by activity in the cerebellum.
<h3>What is meant by the cerebellum?</h3>
The cerebellum, also known as the "little brain" because it resembles a miniature cerebrum, is in charge of balance, movement, and coordination. The pons and medulla, along with the midbrain, are commonly referred to as the brainstem. The brainstem receives, sends, and coordinates messages from the brain.
The cerebellum is the area of the brain in charge of coordinating voluntary movements. It is also in charge of a variety of functions, including motor skills like balance, coordination, and posture.
The cerebellum is important for maintaining balance by making postural adjustments. It modulates commands to motor neurons based on input from vestibular receptors and proprioceptors to compensate for changes in body position or muscle load.
Therefore, the correct answer is option B) cerebellum.
