Transformation of the early reducing atmosphere of the earth into an oxidizing atmosphere was mainly due to the activities of
1 Aerobic photosynthesizers
2 Anaerobic heterotrophs
3 Anaerobic photosynthesizers
4 Annerobic chemoheterotrops
Explanation:
Transformation of the early reducing atmosphere of the earth into an oxidizing atmosphere was mainly due to the activities of aerobic photosynthesizers.

Which is not proved by naturalistic or chemosynthetic theory of origin of life?
1 Formation of coacervates, composed of colloidal
2 Formation of true living cell
3 Formation of macromolecule
4 Formation of macromolecule
Explanation:
. Naturalistic or chemosynthetic theory or origin of life was proposed by A.I. Oparin. They also proposed materialistic theory to understand this biochemical evolution. Concept of this theory can be studied in the following sequence, atomic stage, molecular stage, formation of organic compound and complex organic compound, i.e., formation of micro, and macro molecule and coacervates, component of colloidal nucleoprotein but formation of living cell is not proved by this theory.
