Final answer:
The three pieces of evidence for the endosymbiotic theory are B) Mitochondria, chloroplasts, and prokaryotic features.
Step-by-step explanation:
The three pieces of evidence for the endosymbiotic theory are B) Mitochondria, chloroplasts, and prokaryotic features. Endosymbiotic theory proposes that these organelles were once independent prokaryotic organisms that formed a symbiotic relationship with a host eukaryotic cell, giving rise to the eukaryotic cells we see today. Factors supporting this theory include the similarities between mitochondria and chloroplasts to prokaryotic cells, such as the presence of their own DNA, ribosomes similar in structure to those of bacteria, and the replication method of binary fission which offers a strong resemblance to bacterial cell division.
The three pieces of evidence for the endosymbiotic theory are B) Mitochondria, chloroplasts, and prokaryotic features. A critical piece of evidence for the endosymbiotic theory is that mitochondrial DNA and chloroplast DNA are highly related to bacterial DNA, in both sequence and chromosome structure. The endosymbiotic relationship is believed to have been mutually beneficial, with the host cell gaining increased efficiency in energy production and the endosymbionts gaining a protected environment to thrive in.
