Why can differences in mitochondrial dna be used as derived characters?

Differences in mitochondrial DNA can be used as derived characters since the mitochondria is an organelle that is present in the sperm cells and continues to develop inside the fertilized egg cell. The DNA present in the mitochondria of cell is derived from the parent.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
