What is a disadvantage of asexual reproduction?
a) it leads to the birth of very few offspring at one time.
b) genetic information is passed from parent to offspring, with no genetic variation.
c) it cannot take place until and unless genetic information from two parents is combined.
d) it does not allow the organisms to survive and reproduce during unfavourable conditions.

B) Genetic information is passed from parent to offspring, with no genetic variation. 
Genetic variation makes for stronger offspring. 

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.
