Why is the mouse population changing over time? (You can enlarge the picture by placing your cursor on it.)

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

The graph shows the change in percentages of grey prey in a population over time. What conclusion can be drawn from the graph?

• Grey prey had a high fitness in the mountain rock environment

• There was an increase in mutations in the population

• There was an increase in variation in the population
