HELP I WILL MARK BRAINLIEST BUT YOU HAVE TO BE CORRECT To formulate the Hardy-Weinberg principle, what imaginative leap did both Godfrey Hardy and Wilhelm Weinberg have to make?
They had to imagine what might cause a species to become extinct.
They had to imagine which alleles each new species would have.
They had to imagine a world in which evolution did not happen.
They had to imagine how many offspring an individual could produce.

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.

Ithink you should go back and learn in school rather then here asking questions
