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.
The
molecular clock tracks down nucleotide sequences for DNA or amino acids that
contain sequences of proteins. Scientists use this to deduce the time in
history where life forms possibly have diverged. This technique is also known
as a gene clock or an evolutionary clock.
