<span>Molecular scientists can read the DNA code and compare the DNA of different organisms. This concept is ude in molecular clocks to determine the Moleular Phylogenies. It is letter B. Hereditary molecular differences are being analyzed in phylogeny which is mainly from the DNA sequence in order to acquire information on the evolutionary relationships of an organism.</span>
Humans ferment lactic acid in muscles where oxygen becomes depleted, which is why sometimes if you finish a run and don't stretch soon you have have discomfort. <span />
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
