homework 7 A physiologist wants to know if a hormone affects root growth. She gathersfive "source" plants and takes two cuttings from each plant. For each source plant, she grows onecutting in the presence of a hormone, and she grows the other cutting without the hormone. Shemeasures the length of a root on each of the ten resulting plants after 5 weeks of growth.
