Answer 1

The correct statement regarding how mitochondria were acquired by host cells is:

A bacteria cell was engulfed into a host cell through the process of phagocytosis.

This refers to the endosymbiotic theory, which suggests that mitochondria originated from free-living bacteria that were engulfed by an ancestral eukaryotic cell. Over time, these bacteria became a vital part of the cell, evolving into the mitochondria we see today.
