Sophia learns that the chromosomes in reproductive cells undergo a process called "crossing over," which allows for greater genetic variation in the reproductive cells. She constructs a partial model, as shown, to illustrate the process of crossing over.

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.

That is true it is called an aftershock
