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.

The chappral biome is one of the most widespread biome in the world, it can be found on almost all continents. The major characteristic of the biome include the following:
It has both forest and grassland,
It has two major seasons, winter and summer; the summer season is usually very dry and last for about five months.
The dry summer makes the biome sensitive to fire outbreak, which is a common occurrence there.
The amount of rain available to the biome is about 10 - 17 inches per year and is only able to support shrubs growth, only few trees can be found in the biome.
The biome can be a plain, a rolling hill or a mountain and the soil is usually very dry.
How did the sunflowers depict their rivalry in the image? Why should they fight it out?
The reason I've chosen this as a scientific topic is because the area is covered in sunflowers. With the conditions of their surroundings, living organisms attempt to live. As a result, there is rivalry among the organisms.
