Scientists plan to re-create the origin of life on earth in the laboratory. which of these statements best summarizes their experimental design? select one: a. plants would be created from rocks. b. organisms would be created from fossils. c. bacteria would be created from genetic code. d. living matter would be created from reproducing molecules.

The best answer is D) Living matter would be created from reproducing molecules.

Since the reproduction of organic molecules is generally considered to be the precursor to life on Earth,  the scientists would design an experiment to replicate this. 

Plants were not created from rocks, and fossils indicate previous life, so they would not have been present for life's origin. C is tempting, but genetic code came from the evolution of life, and thus could not be an 'ingredient" for life's origin. 

It would be the equator

Ithink its because more have died recently than in the past.
