12.
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 the insect DNA to spontaneously mutate.

They will shrink because salt will move out of them.

Aerobic respiration results in less energy.
b)
Aerobic respiration results in more energy.

to scare off young birds

The yucca plant releases a strong scent at night when the yucca moth is active. The yucca moth, attracted by the scent, gathers pollen from the yucca flower. The yucca moth then deposits her eggs and the pollen on another plant. This ensures that the plant will be cross-pollinated and that the yucca moth larvae have a steady food supply. Which relationship does this BEST illustrate?
a)
commensalism
b)
mutualism
c)
parasitism
d)
predation
