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:
you would use your muscles from your legs and your body to get up from your bed and go to your fridge, your muscular system helps you up by being a structure for the muscles to apply force, you will use arm muscles for getting out cookies and milk.

Explanation:
Bacteria are the dangerous organisms that can grow in a many different environments and are capable of producing toxic substances which can harm other organisms. This bacteria has the ability to survive in the most extreme environment present near the volcanoes. There are about 30,000 species of bacteria that can live in a variety of environments. There are also some bacteria that is beneficial to humans, animals and plants but they are less in number.
