3. Biologists investigated the effect of the presence of aluminum ions
on root tips of a variety of wheat. They removed 2-mm sections of
the tips of roots. Half of the root tips were placed in a nutrient
solution with aluminum ions, while the other half were placed in an
identical nutrient solution without aluminum ions. The length of the
root tips, in millimeters, was measured every hour for seven hours.
The results are shown in the data table below.
