Answer 1

The best response to demonstrate how modern cells exemplify endosymbiosis is:

**"An amoeba-like organism engulfed prokaryotes, and they eventually became cells, one inside the other."**

This response accurately reflects the theory of endosymbiosis, which posits that certain organelles, like mitochondria and chloroplasts, originated from free-living prokaryotic organisms that were engulfed by a host cell. Over time, these engulfed prokaryotes and the host cell developed a mutually beneficial relationship, ultimately becoming integral parts of eukaryotic cells.
