50. A student concludes that because the Miller-Urey experiment did not produce living cells, it has no scientific value. Which response is most appropriate?

A. The conclusion is correct because only living cells are biologically important.
B. The conclusion is incorrect because the experiment demonstrated a crucial early step in the origin of life by producing organic molecules from inorganic substances.
✓
C. The experiment actually produced bacteria, but they were destroyed.
D. The experiment disproved the concept of chemical evolution.

📝 Explanation

Correct: The Miller-Urey experiment provided strong evidence that life's building blocks can form naturally under simulated primitive Earth conditions. A: Ignores the significance of prebiotic chemistry. C: No living organisms were produced. D: The experiment supports, rather than disproves, chemical evolution. Concept: Significance of the Miller-Urey experiment.
