Environmental changes (such as a natural disaster) may cause adaptive responses in organisms, such as the Galapagos finches. Due to the islands getting hard-hit by natural disasters, the once-same species of finch were isolated in separate islands. Each generation, through natural selection, adapted to their new environment. For example, their wingspans differed, and their beak shape adapted to their source of food in their separate environments (ranging from big beaks for seeds to narrow beaks for insects).
The anaerobic cellular systems or anaerobic respiration use fermentation because the anaerobic cellular systems oxygen is absent. Fermentation takes place in the absence or in the partial pressure of oxygen to produce alcohol or lactic acid. This is the way of production of ATP which is need for various cellular processes.
If fermentation was not there, then the anaerobic cellular systems could not produce energy and the cellular processes could not occur. In the absence of fermentation, no ATP would be produced and the cells would gradually die.

Answer:
The sex cells could not easily combine to form the body cells of an offspring because of the different chromosome number.
