Step-by-Step Analysis
The question presents a two-part fill-in scenario about the origin of eukaryotes and the identity of the endosymbiotic ancestor.
First blank options to consider are anaerobic vs aerobic. The statement reads: 'Eukaryotes likely originated from [Select] archaebacteria that engulfed but did not digest, [Select] eubacteria.' The widely supported endosymbiotic theory posits that an anaerobic archaebacterium (one that did not rely on oxygen) engaged in a symbiotic relationship with an aerobic......Login to view full explanationLog in for full answers
