In a population of clover flowers, there are both white and purple varieties. The cows that graze the field where the clovers grow prefer the purple variety. Over time, the white clover flowerAccording to the primordial soup model, the first organic molecules could have formed from simpler inorganic substances in Earth’s early oceans, but only if there were a source of energy to cause such chemical reactions to take place. Which are possible sources of energy that could have led to the production of these first precursors to life? (SC.912.L.15.8)

Over time, the white clover flowerAccording to the primordial soup model, the first organic molecules could have formed from simpler inorganic substances in Earth’s early oceans, but only if there were a source of energy to cause such chemical reactions to take place.

photosynthesis and cellular respiration
solar radiation, volcanic eruptions, and lightnings become much more numerous and the purple ones more scarce. This is an example of what process? (SC.912.L.15.13)

Answer 1

The possible sources of energy that could have led to the production of the first precursors to life are solar radiation, volcanic eruptions, and lightning.

The process described where white clover flowers become much more numerous and purple ones more scarce due to cows preferring the purple variety is an example of natural selection.
