Question

The hypothesis that explains the origin of eukaryotic cells as the result of two or more simpler cells developing a relationship with one another is called:

1) panspermia.
2) symbiosis.
3) evolution theory.
4) endosymbiont theory.

Answer 1

The hypothesis that explains the origin of eukaryotic cells as the result of two or more simpler cells developing a relationship with one another is called 4) endosymbiont theory.

Step-by-step explanation:

The hypothesis that explains the origin of eukaryotic cells as the result of two or more simpler cells developing a relationship with one another is called endosymbiont theory. According to this theory, eukaryotes evolved from a symbiotic relationship between prokaryotic cells. Specifically, smaller prokaryotic cells were engulfed by larger prokaryotic cells and eventually evolved into organelles of the host cells. This theory is widely accepted and supported by evidence.
