Question

If you wanted to add a column for the protist species Amoeba proteus, what taxonomic category, if any, would it have in common with the other organisms in the chat?

Answer 1

I believe the answer is No; It would not share any taxonomic category with any other organisms in the chat; simply because it is in a different kingdom.
Amoeba are eukaryotes whose bodies most often consist of a single cell. The cells of amoebae, like those of other eukaryotes, possess certain characteristic features. Their cytoplasm and cellular components are enclosed within a cell membrane.
