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:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
A scientific law would be your answer.
There are many laws that are defined using formulas.

Yes of course!
In the most catastrophic case, it can kill hundreds of thousands through hurricanes and the things that come with hurricanes.
Droughts can cause death by both dehydration and starvation if the rain is the only dependable source of arrogation
Too much rain causes floods which can be fatal too
