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.

Which term describes the perception of the body's movement through space?
A. nociception
B. neurasthenia
C. kinesthesia
D. dimensionality
Solution

Whenever a person senses his/her body movement through space or any other kind of physical bodily movement or action, he/she actually faces Kinesthesia. This is also related with the Charles bell concept of sixth sense through which one could perceive sensation of static position or velocity of the movement
