Question

if eukaryotes all came about due to endosymbiosis, what would result from that? (1 point)
every organism would have the same set of body systems and functions
preserved dna from the original ancestor that remains unchanged
similar structures in eukaryotes with slight variations depending on their use
ancient prokaryotes living inside of modern eukaryotes

Explanation:

Endosymbiosis theory states eukaryotes evolved when large cells engulfed smaller prokaryotic cells that became permanent organelles (like mitochondria, chloroplasts). These engulfed prokaryotes evolved into modern organelles, meaning ancient prokaryotes-like structures live inside modern eukaryotes. The other options are incorrect: not all organisms have identical body systems, ancestral DNA accumulates changes over time, and eukaryotic structures have significant functional differences beyond slight variations.

Answer:

ancient prokaryotes living inside of modern eukaryotes
