Options

A. Oparin
B. Sydney Fox
C. Haldane
D. Bondi

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks who named microspheres. The options provided are Operin, Sidney Fox, Haldane, and Bondi.

2. **Identifying the Correct Answer**: From the information provided, Sidney Fox is identified as the person who named microspheres.

3. **Explaining Microspheres**: Microspheres are tiny spherical structures formed by the aggregation of proteins. They resemble cell-like structures but do not possess all the properties of living cells.

4. **Significance of Sidney Fox's Work**: Sidney Fox conducted experiments that demonstrated the possibility of creating protein-like structures from inorganic molecules using thermal energy. His work suggested that these microspheres closely resembled bacterial cells and could represent early forms of life, termed protocells.

5. **Clarifying Other Options**:
- **Operin**: He introduced the term "coacervate," which is different from microspheres.
- **Haldane**: He proposed ideas about the origin of life and referred to the primitive earth but did not name microspheres.
