Origin Of Life

Step 1: Micelles and coacervates are types of colloidal aggregates. Micelles are formed when amphipathic molecules, such as lipids, aggregate in water, with hydrophobic tails inward and hydrophilic heads outward. Coacervates are phase-separated aggregates of proteins or other macromolecules in aqueous solution.

Step 2: Micelles are formed by lipids, and coacervates are formed by proteins. Both are examples of nonliving colloidal aggregates, with their respective structures contributing to their biological functions.

Conclusion: The correct answer is micelles for lipids and coacervates for proteinoids.

In the Miller-Urey experiment (1953), a mixture of gases that was thought to represent the early Earth's atmosphere was subjected to electrical discharges to simulate lightning. The gas mixture used was composed of hydrogen (H ), methane (CH ), and ammonia (NH ) in a 2:1:1 ratio, which produced amino acids and other organic compounds. Thus, the correct answer is 2:1:1 (H : NH : CH ).
