You’ve done a large series of experiments, growing different combinations of crop plants together. suppose you changed this lab's experimental design. which of the following changes would probably not change the results?

a. substituting slow-growing lettuces for rutabaga and mustard.
b. letting the plants grow for twice as long, so some of the "fast-starters" slow down growth and "slow-starters" speed up.
c. restricting water and/or nutrients, instead of supplying ample quantities of both.
d. adding leaf-eating caterpillars that prefer rutabaga.
moving the trays farther apart in the greenhouse, so the edges don't touch one another.
