Why aren't macromolecules currently being produced in our oceans ?

In chemical evolution happens, all the required environment was there ! But now, the exact environment is not present !

the environment concludes: H2 (not present due to light weight) , methane, NH4 and water vapour ! and most important that is not present is the 40,000 volts of lighting, that was normal at that moment !

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.

The answer is c. they had seedshope this
