Question

origins of life
below are several hypotheses governing the first two stages of the origins of life. label each hypothesis accordingly
boxes: iron sulfur world hypothesis, primordial soup hypothesis, protein first hypothesis, extraterrestrial origins hypothesis, rna first hypothesis
descriptions:

1. dissolved gases such as carbon monoxide, ammonia, and hydrogen sulfide rise from thermal vents and pass over iron and nickel. the resulting sulfides act as catalysts to drive the evolution of organic molecules from inorganic molecules.
2. earth contains water, hydrogen, methane, and ammonia, creating a reducing atmosphere so that redox reactions drive the abiotic synthesis of organic molecules from inorganic molecules.
3. amino acids present in shallow puddles along ocean shores are heated by the sun to form proteinoids with catalytic properties.
4. meteorites carrying organic molecules seeded the earth with organic molecules.
5. organic molecules react with iron and nickel sulfides at thermal vents to produce peptides.
6. organic monomers evolve into rna, which functions as a catalyst to direct the formation of other molecules.

Explanation:

To solve this, we match each description to the correct hypothesis:

1. First left description (Dissolved gases... iron and nickel...):

This matches the Iron - Sulfur World Hypothesis (involves thermal vents, iron/nickel, and sulfides as catalysts for organic molecule evolution).

2. First right description (Earth contains water... abiotic synthesis...):

This matches the Primordial Soup Hypothesis (describes early Earth’s atmosphere and abiotic synthesis of organic molecules).

3. Second left description (Amino acids... shallow puddles... proteinoids...):

This matches the Protein First Hypothesis (focuses on amino acids forming proteinoids with catalytic properties).

4. Second right description (Meteorites carrying organic molecules...):

This matches the Extraterrestrial Origins Hypothesis (organic molecules from space “seeding” Earth).

5. Third left description (Organic molecules... iron and nickel sulfides... peptides...):

This also relates to the Iron - Sulfur World Hypothesis (interactions at thermal vents to form peptides).

6. Third right description (Organic monomers... RNA... catalyst...):

This matches the RNA First Hypothesis (RNA as the first catalytic and informational molecule).

Final Labeling (matching each box to the hypothesis):

• Top - left box (first description): Iron - Sulfur World Hypothesis
• Top - right box (first description): Primordial Soup Hypothesis
• Middle - left box (second description): Protein First Hypothesis
• Middle - right box (second description): Extraterrestrial Origins Hypothesis
• Bottom - left box (third description): Iron - Sulfur World Hypothesis
• Bottom - right box (third description): RNA First Hypothesis

6. Third right description (Organic monomers... RNA... catalyst...):

This matches the RNA First Hypothesis (RNA as the first catalytic and informational molecule).
