New folder New folder ogy Posttest Spring 2021 Question 32 II Pause Zoom A man treated his home with a pesticide that kills roaches. The first application of the pesticide killed 92% of the roaches. Two months later, he applied the same pesticide to his home again, but the second application killed only 65% of the roaches. What would best explain the decrease in the effectiveness of the pesticide? The pesticide is effective only against mature roaches. The pesticide caused some of the roaches to mutate and metabolize the pesticide. The pesticide lost its effectiveness over a period of time The surviving roaches were naturally resistant to the pesticide and that resistance was inherited by their offspring 02021 luminate EducationM Inc.
