which of the following is the best explanation of the process that caused mosquito populations in africa to become resistant to ddt? group of answer choices the immune systems of mosquitoes exposed to ddt developed resistance. these mosquitoes passed some of this resistance to their offspring so that each generation of mosquitoes became more likely to survive exposure to ddt. some mosquitoes were fortunate to be naturally able to survive exposure to ddt (even though ddt had never been used in their area before), and passed this ability to their offspring. the mosquitoes became resistant, because if they did not, they would die. ddt caused widespread mutations in the dna of mosquitoes.
