15.
The use of pesticides on crops has been a common farming practice for decades. What has been the greatest effect of natural selection through the use of pesticides on certain insect populations?
a)
Natural selection has been altered because the insects and their predators are killed.
b)
The rate of selection is increased because the pesticides do not kill the insects that are naturally resistant to it.
c)
The rate of selection has decreased because the pesticides kill only young insects.
d)
The pesticides have altered natural selection by causing teh insect DNA to spontaneously mutate.
