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 pesticide to this 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 Mountain Hare was introduced to Faroe Island from Norway in 1854. During the first years, some of the hares developed a white coat in winter, like their ancestors from Norway, but after a few decades, due to the oceanic climate with its lack of snow cover, the Faroese Hares population was staying brown all year.
