Hydrothermal vents are associated with the newest theory on early cell evolution.Which of the following is a true statement?
A)Synthesis of organic material occurs in superheated mineral rich water.
B)Iron-sulfide molecules may act as cofactors for organic material production.
C)Rock formed under these conditions has small pits about the size of an average cell.
D)Under these conditions iron sulfide would donate hydrogen to carbon dioxide to form organics.
E)All of these are true.

Question

Quizplus · Accepted Answer

All of these statements are true based on current knowledge of hydrothermal vents and their association with early cell evolution. Organic material synthesis, often through the process of chemosynthesis, can occur in superheated mineral rich water, and iron-sulfide molecules may act as cofactors. Rock formed under these conditions has been found to contain small pits that are similar in size to an average cell, and iron sulfide can donate hydrogen to carbon dioxide to form organics.
