Question

select the scientific theories which connect early earth conditions related to lifes origin. hydrothermal vent communities occurred in surface waters, and early photosynthesis helped change inorganic molecules into organic molecules. rna may have formed in clay material like montmorillonite and then dna evolved from rna, eventually taking on important roles millions of years later when eukaryotic cells formed. the clay material montmorillonite may have been a source where inorganic molecules could have changed into organic molecules. hydrothermal vent communities may have been a source where toxic gases, like methane, were present and inorganic molecules could have changed into organic molecules.

Explanation:

Hydrothermal vent communities and clay - like montmorillonite are associated with early Earth conditions for life's origin. Hydrothermal vents could have provided an environment for the transformation of inorganic to organic molecules, and clay materials like montmorillonite may have been sites for such chemical changes and also for RNA formation. RNA evolving to DNA is also related to the development of life on early Earth. Early photosynthesis occurred in the oceans and not in surface waters as stated in the first option, making it incorrect.

Answer:

B. RNA may have formed in clay material like montmorillonite and then DNA evolved from RNA, eventually taking on important roles millions of years later when eukaryotic cells formed.
C. The clay material montmorillonite may have been a source where inorganic molecules could have changed into organic molecules.
D. Hydrothermal vent communities may have been a source where toxic gases, like methane, were present and inorganic molecules could have changed into organic molecules.
