The condition in which an organism has extra sets of chromosomes is called polyploidy.

The statement above is a true statement. The condition in which an organism has extra sets of chromosomes is called polyploidy. This polyploidy cell is an organism that has two sets of chromosomes.  Most species have two sets of chromosomes, each one of these are inherited from the parents.

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.
