Ascientist discovers a new organism in run-off from the rio tinto river in spain (the river runs through a copper mine and the water has a ph of 2.0). on basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. given this information, this new species is most likely a cell in the subcategory

A scientist discovers a new organism in run-off from the Rio Tinto River in Spain (the river runs through a copper mine and the water has a pH of 2.0). On basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. Given this information, this new species is most likely a eukaryotic cell in the protozoan subcategory

Explanation:

Eukaryotic cells contain nucleus and organelles and are enclosed by a plasma membrane. Organism that have these cells are protozoa, fungy, plants and animals.

Protozoan are single-celled eukaryotic.

the fossil record provides evidence of a common ancestor to many species.
