Bromothymol blue is an indicator dye that turns yellow in presence of an acid. It remains blue if the pH of the given solution is greater than 7.6 and yellow when the pH is less than 6. The yellow coloration is due to the formation of carbonic acid in the from the carbon dioxide present in the solution.
When aquatic plants are added to two test tubes containing bromothymol blue, stoppered and kept in dark for two days, no color change is observed. It is because the carbon dioxide present is utilized in the process of photosynthesis by plants. If the experiment is conducted in presence if the light, the color of bromothymol blue would be yellow due to the presence of carbon dioxide.
Karyotypes were first performed using blood samples taken from youngsters and adults. Later, a pre- birth process called amniocentesis was developed which allowed medical researchers to obtain samples of cells from extraembryonic fluid located in the amniotic sac, which surrounds an unborn child.

Water is critical in all life. This is because it is important in the biochemical process of the cell. Take an example; water is consumed in most hydrolysis reaction in the body and is also significant in the regulation of blood pressure. Therefore even microbial activity will be reduced during water scarcity. Subsequently, nitrification process by nitrifying bacteria will definitely reduce in dry summers.
