Farmers cross pumpkins to specifically have a round shape and deep orange color. This has been done to pumpkins since before DNA was discovered and therefore, requires no genetic modification in a laboratory. Which form of genetic engineering is most likely used by farmers to create pumpkins with a round shape and deep orange color?

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.
