Hydrothermal Vents Deep in the Ocean, Where Hot Water Emerges

Multiple Choice

Hydrothermal vents deep in the ocean, where hot water emerges from beneath Earth's crust, lack oxygen gas and contain metals such as iron and nickel.This is important for understanding the chemical evolution of life on Earth because

A) deep water hydrothermal vents were very common on early Earth.
B) iron and nickel can catalyze amino acid polymerization under anaerobic conditions.
C) hydrothermal vent environments produce large quantities of ribozymes.
D) evaporation of hydrothermal vents can concentrate monomers to the point that they polymerize.
E) lack of oxygen is essential for polymerization of large quantities of monomers into a single chain.
