Explain why species with a diverse gene pool are usually less threatened by environmental change than are species whose members all have similar genes.

They are less threatened because they are more adapted to their environment therefore will survive drastic environmental change. This is because they are more diverse: they have evolved more.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
