ZanzabumX [31]

Answer:

I think she should try the experiment one set with fertilizer, and one without. The negative control group would be the set of rose bushes grown without the fertilizer, but under the exact same conditions as the experimental group.

Radda [10]

Answer:

The endosymbiotic theory

Explanation:

Protists are the multicellular organisms which possess characteristics of both the prokaryotes and eukaryotes.

The protist can derive nutrition by either heterotrophic mode or photoautotrophic mode. This variation could exist within the same genus and same species.

This variation could be explained with the endosymbiotic origin of the organisms as some species could engulf the photosynthetic bacteria whereas some could have engulfed the chemosynthetic bacteria.

This can be observed in the green and red algae which depend on a different mode of nutrition belonging to the same group.

Thus, the endosymbiotic theory is correct.
