Prokaryotes and eukaryotes package their DNA molecules with protein in structures called chromosomes. A prokaryotic chromosome is circular and resides in a cell region called the nucleoid.
Answer:
The correct option is 'the ability to absorb other cells gave some prokaryotes a survival advantage.'
Explanation:
The scientists have brought forward the theory of endosymbiosis which explains how eukaryotic cells evolved from prokaryotic cells. According to this theory, the scientists claim that the organelles found today in the cells, once existed as individual prokaryotic cells. These organelles were engulfed by larger prokaryotic cells with time and hence, the eukaryotic cells evolved from these prokaryotic cells. The larger prokaryotes might have engulfed the smaller cells for survival.
