Question

which sequence correctly describes the hypothesized steps in the origin of life on earth?
formation of protocells → abiotic synthesis of organic molecules → origin of self - replicating molecules → formation of macromolecules
abiotic synthesis of organic molecules → origin of self - replicating molecules → formation of macromolecules → formation of protocells
origin of self - replicating molecules → formation of macromolecules → abiotic synthesis of organic molecules → formation of protocells
abiotic synthesis of organic molecules → formation of macromolecules → formation of protocells → origin of self - replicating molecules

Explanation:

The hypothesized origin of life starts with non-living processes making simple organic molecules (abiotic synthesis). These small molecules then combine to form larger macromolecules. Next, self-replicating molecules (like RNA) emerge, allowing inheritance. Finally, these components are enclosed in protocells, the precursors to living cells.

Answer:

Abiotic synthesis of organic molecules → Formation of macromolecules → Origin of self-replicating molecules → Formation of protocells
