According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food?
A.
The host cell would have been poisoned if it had digested the engulfed cell.
B.
The host cell was able to survive anaerobic conditions with the engulfed cell alive.
C.
