Question

A researcher discovers a new microfossil. At first, he is uncertain whether this organism was a bacterium , Archaeon, or protist. After careful study, he determines that this organism was a protist. What features were present in this microfossil that lead the researcher to this conclusion?

Answer 1

Exclusive features from Protozoa

Step-by-step explanation:

Protozoa are unique and complex single-celled eucaryot. So, if the discovered microfossil still has some clues of a presence of a nucleus it might be a feature that can be related with only with a protist organism. Also, some protozoa has special anatomy structures like sensory bristles, photoreceptors, cilia, sting darts, etc. In conclusion there might be some features that could lead researchers to find a new extinct protist organism.
