Protists are eukaryotic organisms that are primarily unicellular and microscopic. They are mostly aquatic, and examples of protists include amoeba, diatoms, dinoflagellates, plasmodium and many more.Answer and Explanation: Three examples of protist symbiosis: Symbiosis with corals: In this symbiosis, ...
Of the three broad groups of protists, which are heterotrophs and which are autotrophs? What are the two common characteristics of the clade Lophotrochozoa? Were members of the clade Testudines alive around the time of the dinosaurs?

The current Three Domain System groups organisms primarily based on differences in ribosomalRNA(rRNA) structure. Ribosomal RNA is a molecular building block forribosomes. Under this system, organisms are classified into three domains andsix kingdoms. The domains are ...
The release of EVs to the extracellular space is probably con- served in all types of eukaryotic cells: animals, plants, protists and fungi, be they either in unicellular or multicellular organ- isms; however, most studies to date have been done in animals, specifically...

These studies, based on 18S ribosomal RNA (rRNA) gene sequence analyses, revealed considerable diversity and the existence of novel groups of sequences unrelated to cultured and sequenced organisms. Surveys of picoplank- tonic protists, by sequencing the 18S rRNA gene in different environmental ...
TK exhibits a complex phylogenetic distribution across different groups of eukaryotes. Metazoa and ciliates have a highly divergent form of TK characterized by many gaps and deletions; we have not included these sequences in our data set because they are difficult to align with other TKs. Most eu...
