2 In dry desert areas poor drainage can lead to a buildup of salt in water supplies. A student performed an investigation to study the effects of
salinity on the germination rates of seeds. The student placed seeds in
several solutions containing 0% to 3% salt. The length of the radicle, which is
the root of the germinating seed, ranged from 49 mm in the 0% salt solution
to 0 mm in the 3% salt solution. The data from this investigation suggest
that increased salinity in more areas may lead to a decrease in which

correct answer: understand the different control methods available
