Coacervates are certain complex inorganic and organic compounds in the hot sea water aggregated in different combinations. Who called them microsphere ?

Options

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

Answer

To answer the question "Who called coacervates microsphere?", we can follow these steps:

### Step 1: Understand the concept of coacervates
Coacervates are complex aggregates of organic and inorganic compounds that form in aqueous environments, particularly in hot sea water. They consist of macromolecules such as proteins and nucleic acids.

### Step 2: Identify the key characteristics of coacervates
Coacervates are formed through a process known as liquid-liquid phase separation (LLPS), where macromolecules come together in a specific aqueous environment.

### Step 3: Look at the options provided
The options given are:
1. Haldane
2. Operin
3. Sydney Fox
4. Witcher

### Step 4: Recall the contributions of the scientists
- Haldane and Operin are known for their work on the origin of life and primordial soup theories.
- Sydney Fox is recognized for his research on coacervates and their significance in the origin of life.
- Witcher is not widely recognized in this context.

### Step 5: Conclude the answer
Based on the contributions of these scientists, it is Sydney Fox who referred to coacervates as "microspheres" due to their characteristics.

### Final Answer
The correct answer is **C. Sydney Fox**.
