supplementation because they are the same
plant.
B. it would respond completely differently to
nitrogen supplementation because they are
different strains.
C. it could respond the same way or
differently; different genotypes can, but may
not always, respond differently to the same
range of environments.
D. it could respond the same way or
differently; the environment has too many
variables to predict.
E. None of these choices is correct.
