Solution

29. A) pesticides and other toxins released into the environment to kill mosquitoes may not be specific and have unintended consequences.

Option B does not comply with the question that is to cause mosquito species go extinct and not about already infected people. Option C seems to be irrelevant.

30. A) Merozoites

If a stage other than merozoites is targeted, the merozoites can lead further to the formation of gametocytes which produce gametes and so on.

31. D) the protest cells terminally differentiate in the mosquito and need to reset their developmental stages in mammalian cells.
