Question

What must be true if prokaryotes evolved into eukaryotes by endosymbiosis?

A. The formation of amino acids gave a survival advantage.
B. The ability to absorb other cells gave some prokaryotes a survival advantage.
C. Having genetic material gave a survival advantage.
D. Being unicellular gave a survival advantage.

Answer 1

B

Step-by-step explanation:

The evolution of eukaryotic cells is explained by the endosymbiotic theory i.e. when large cells engulfed smaller cells in a process called phagocytosis. The theory further explained that these engulfed small cells were not broken down but instead lived as organelles in the large cells forming a symbiotic relationship.

Since the endosymbiotic theory of eukaryotes evolution is simply based on the engulfing of one cell, hence, the absorbing ability is the survival advantage.
