Mitochondria are thought to have evolved from ancient bacteria. Free-living bacteria have lost motility in mitochondria over time.
<h3>What is endosymbiosis?</h3>
- Endosymbiosis is the term used when one organism truly lives inside the other. According to the endosymbiotic theory, it is simple for a big host cell and ingested bacteria to become dependent on one another for survival and develop a long-term bond.
- Due to their increased specialization through millions of years of evolution, mitochondria and chloroplasts can no longer survive outside of cells.
- Chloroplasts and mitochondria are remarkably similar to bacterial cells. They have unique DNA that is distinct from the DNA found in the cell's nucleus.
- Additionally, these organelles synthesize numerous proteins and enzymes necessary for their functions using DNA. Both mitochondria and chloroplasts are surrounded by a double membrane, which is additional proof that each was ingested by a primitive host.
- Similar to bacteria, the two organelles also divide by themselves and replicate their own DNA.

ANSWER: C, the continents were at one time joined together.
REASONING: Alfred Wegener was the first person to propose the scientific theory of Continental Drift. Continental Drift is a theory that supposes all the continents were at one time joined together as one large land mass. The mechanisms of continental drift can be explained by Plate Tectonics.
