New species develop when a) diverging species no longer recognize one another as potential mates. b) diverging species mate exclusively. c) diverging species mate with multiple members of the other species. eliminate d) diverging species recognize many potential mates among both species.

A new species develops when the two diverging species no longer recognize each other as their potential mates. In such cases, these two species evolve and grow as two completely different species. There is no genetic exchange between these two species now.  When two species diverge, there are no chances of of the members of each of them mating as there DNA (Deoxyribonucleic acid) is no longer compatible.

Hence, the correct answer is 'Option A - diverging species no longer recognize one another as potential mates'.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
