A group of researchers run an experiment to determine the effect of mycorrhizae (a fungu on plant growth. The researchers set up thre experimental groups: A large amount of mycorrhizae is applied to the plants in group a smaller amount of mycorrhizae is applied t the plants in group 2, and no mycorrhizae is applied to the plants in group 3. Which group(s) is/are the experimental group(s)? More than one answer may be correct. Select all that apply.

Transcribed Image Text:A group of researchers run an experiment to
determine the effect of mycorrhizae (a fungus)
on plant growth. The researchers set up three
experimental groups: A large amount of
mycorrhizae is applied to the plants in group 1
a smaller amount of mycorrhizae is applied to
the plants in group 2, and no mycorrhizae is
applied to the plants in group 3.
Which group(s) is/are the experimental
group(s)? More than one answer may be
correct. Select all that apply.
