The average menstrual cycle is 28 days long but can vary from 24 to 38 days. If a menstrual cycle is shorter, a person can have a period more than once a month.
So that there is more gene variation. Let's say if they all had the same genes, one specific disease would be fatal for the species' existence since they would all be the same. The diverse gene pool allows species to develop different characteristics that can help them defend against disease

Polysaccharide formation allows organism to store energy efficiently. The storage form of food in animals is glycogen and in plants it is starch. Both glycogen and starch are polysaccharides of glucose. Many glucose units are linked together by condensation reaction to form polysaccharide. Compared to having several molecules of glucose in a bulk it is better to store it in the form of condensed bulk i.e polysaccharide. Thus polysaccharides which are formed by condensation reaction i.e by the loss of water molecules are easy to store.
Polysacchrides are: a) stored in the form of condensed bulk
b) they are chemically non-reactive
c) they are osmolytically inactive
