This document contains definitions of various biological terms: 1) Primates are characterized by features of the hand or front foot, specifically opposable thumbs. 2) Protists exhibit two types of cell cleavage - Protosome exhibit cleavage and duetrostomers exhibit cleavage. 3) Viruses are coated fragments of DNA or RNA that have become detached from cell genomes and can replicate within cells.
