Nto which kingdom would you classify a newly discovered unicellular, eukaryotic organism that moves using a flagellum?

The answer is Protist. Oganisms in this group are referred to as unicellular "animal-like" protozoa. They are later classified into ciliated, flagellated, phagocytic, and spore-forming. This group is reserved for microscopic organisms while Protoctista groups multicellular eukaryote organisms such as slime molds.

(since you didn't attach the family tree this is just an assumption)

the correct answer is - ability to find a mate
