To control hormone levels to prepare the body for pregnancy.
They have hormone specific receptors which bind the hormone and initiate a cellular response.
Protein and peptide hormones, catecholamines like epinephrine, and eicosanoids such as prostaglandins find their receptors decorating the plasma membrane of target cells.
Answer:
This is a process whereby the better 'fitted' or adapted varieties of species in populations are selected by environmental pressures. This affects the survival and reproduction of the individuals in the plant/ organism populations in such a way that eventually a variety better adapted to the drier climate dominated the population.
Natural selection is a never-ending process in nature since some environmental factor keeps on changing all he time.
