The correct Answer is:
To solve the question, we need to identify who proposed and supported the idea that primitive organisms evolved spontaneously from inorganic matter due to various physical forces. Let's break down the solution step by step: ### Step-by-Step Solution: 1. **Understanding the Question**: The question refers to a theory about the spontaneous generation of primitive organisms from inorganic matter, influenced by physical forces such as electric charges and UV radiation. 2. **Identifying Key Scientists**: The question provides four options with names of scientists. We need to determine which group of scientists is associated with the theory of the spontaneous generation of life from inorganic matter. 3. **Recognizing the Correct Theory**: The theory that aligns with the spontaneous generation of life from inorganic compounds is primarily associated with A.I. Oparin and J.B.S. Haldane. They proposed that life originated from simple organic compounds formed through chemical reactions driven by physical forces. 4. **Supporting Evidence**: Oparin and Haldane's hypothesis was later supported by experiments conducted by scientists like Stanley Miller, which demonstrated the formation of organic molecules under conditions thought to resemble those of early Earth. 5. **Conclusion**: Based on the information, the correct answer to the question is that the theory was proposed by A.I. Oparin and supported by J.B.S. Haldane. ### Final Answer: The correct answer is: **A.I. Oparin and J.B.S. Haldane**.

Positive and negative ions are produced in the atmosphere due to cosmic rays from space and also due to radioactive elements in the soil. In some region in the atmosphere, the electric field strength is 100 V//m in the vertically downward direction. This field exerts force on the positive and negative ions in the given region in atmosphere. As a result, positive ions, having a density 500//cm^(3) drift downward while negative ions, having a density 300//cm^(3) drift upward. All these ions are singly charged. It is observed that the conductivity in the given region is 4 xx 10^(-13)(Omega - m)^(-1) . Find the average speed of ions, assuming it to be the same for positive and negative ions.
