Coacervates were large colloidal aggregates named by

Options

A. Haldane
B. Oparin
C. Preyer
D. Bondi

Answer

**Step-by-Step Solution:**

1. **Understanding Coacervates**: Coacervates are defined as large colloidal aggregates that form in a solution. They are significant in the study of abiogenesis, which is the origin of life from non-living matter.

2. **Historical Context**: The term "coacervate" was introduced in the context of theories regarding the formation of life on Earth. Various scientists have contributed to the understanding of coacervates, but one of the key figures is Alexander Oparin.

3. **Identifying the Right Scientist**: Among the names mentioned (Haldane, Oparin, Trier, and Bondy), Oparin is the one who specifically named and studied coacervates. His work focused on the formation of these aggregates in the primordial environment.

4. **Role of Coacervates**: Coacervates are thought to play a crucial role in the development of life by providing a medium where complex organic compounds could interact and undergo chemical reactions, leading to the emergence of life.

5. **Conclusion**: Therefore, the correct answer to the question "Coacervates were large colloidal aggregates named by" is **Oparin**.

**Final Answer**: Coacervates were large colloidal aggregates named by **Oparin**.
