Either type of reproduction will result in the continuation of a species, but one method results in genetic variation as well. all but one is a reason why sexual reproduction better serves survival of the fittest and evolution of a species.

The answer to your question is A :). I came across the same question and I found that A was the right answer

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.
