Answer 2

Ivy Acosta

Because of fundamental differences in their cellular structures, biochemistry, and evolutionary histories, protists and bacteria are classified into different domains: protists belong to the domain Eukarya, which includes organisms with eukaryotic cells that contain a nucleus and membrane-bound organelles, while bacteria belong to the domain Bacteria, which is characterized by prokaryotic cells lacking a nucleus and membrane-bound organelles. These differences in classification reflect important differences in their genetic makeup, cellular organization, and evolutionary relationships.
