The prevalence of iron-sulfide cofactors in organisms supports the hypothesis that life arose _____.

A) in outer space
B) on tidal flats
C) near geothermal vents
D) in the upper atmosphere
E) in volcanic springs

Iron-Sulfide Cofactors

Components found in various enzymes and proteins, essential for catalyzing redox reactions, particularly in electron transport chains.

Geothermal Vents

Openings in the Earth's surface from which heated water and gases are discharged, often found in areas with volcanic activity, contributing to diverse ecosystems in the deep sea.

Tidal Flats

Broad, flat areas of land alternately covered and exposed by the rise and fall of tides, rich in biodiversity and important ecologically.
