Afruit fly has four chromosomes. the zygote formed by the sperm and the egg of fruit flies will have chromosomes.

If a fruit fly has four chromosomes then they would only pass on half of their chromosomes to the offspring. The new fly would have gotten 2 chromosomes from the father and 2 from the mother making it 4 chromosomes in total.

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.
