A farmer observes that increasingly higher concentrations of a particular pesticide have been required each year over the past ten years to achieve the same level of effectiveness on a specific insect pest. Which of the following best helps explain the observation?
Some individual insects live longer than others and pass on traits acquired during their lives.
Only the most aggressive and territorial insects survive and reproduce.
Some individual insects are more likely than others to survive and reproduce due to their inherited traits.
Some individual insects produce many offspring, and thus their offspring live longer.
Some individual insects reproduce before the pesticide is applied, thereby avoiding its harmful effects.
