Let's evaluate each of the statements regarding the role of natural selection in pesticide resistance:
a. **Resistance to pesticides develops in a single generation.**
- **FALSE**: Pesticide resistance typically develops over multiple generations. It is often the result of natural selection acting on genetic variation within a population, where individuals that have mutations allowing them to survive pesticide exposure are more likely to reproduce.
b. **Hundreds of species of insects are now resistant to chemical pesticides.**
- **TRUE**: Many species of insects have developed resistance to various chemical pesticides over time.
c. **DDT was effective in decreasing the mosquito population.**
- **TRUE**: DDT was widely used and effective in reducing mosquito populations, particularly in controlling diseases like malaria, although the issues of resistance and environmental impact became significant concerns.
d. **Organisms that are "pesticide resistant" cannot survive and reproduce after being exposed to a pesticide.**
- **FALSE**: Pesticide-resistant organisms can survive and reproduce after exposure to a pesticide, which is precisely how resistance spreads in a population.
Based on the evaluations:
- The **FALSE** statements are:
- a) Resistance to pesticides develops in a single generation.
- d) Organisms that are "pesticide resistant" cannot survive and reproduce after being exposed to a pesticide.
