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. What is the independent variable in this experiment?

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.
What is the independent variable in this
experiment?

eukaryotic cells? More than one answer may
be correct. Select all that apply.
Eukaryotic cells have membrane-bound
organelles but prokaryotic cells do not.
