A grasshopper population in a prairie is limited in large part by the number of birds in

population exhibits exponential growth. This happens because the grasshoppers
experienced

Researchers wanted to determine if pesticide Z was effective at killing grasshoppers
that typically invade cornfields. Two ten-acre cornfields located 1 mile apart were
chosen. The cornfield to the west was sprayed only with water. The cornfield on the
east received the same amount of water with a 10% solution of pesticide Z. Samples of
the numbers of grasshoppers in the field were made every week for 10 weeks. They
found that the number of grasshoppers doubled after ten weeks in the west field treated
only with water. They also found that the number of grasshoppers declined by 50% after
10 weeks in the East field treated with water and pesticide Z. Which field was the
control group?
, a. There were no controls in this experiment.
b. The west field was the control group.
c. The east field was the control group.
d. Both fields were controls for one another.
