Answer:
1. Alexander Oparin's and J. B. S. Haldane's
2. Methane (CH4)
3. Simulate
4. Sparkling device
5. Lightning storm
6. brown broth rich in amino acids
7. Reducing
8. spontaneous organic compound
9. Amino acids.
Explanation:
Miller and Urey performed experiments to support the "Alexander Oparin's and J. B. S. Haldane's" hypothesis. In their experiment, they combined "Methane (CH4)," ammonia, hydrogen gas, and water in a closed system and "Simulate" it to mimic conditions on early Earth. After stimulating the system with a "Sparkling device" to mimic "Lightning Storm, " they discovered that "brown broth rich in amino acids" was produced. This suggests that early Earth had a "Reducing" atmosphere, leading to redox reactions that catalyzed the "spontaneous organic compound" synthesis of organic monomers such as "Amino acids."
Free market because it is a system based on demand with little or no goverment control.
Central Siberian Plateau this is because of the subarctic climate (really cold and extreme) and the ground is often frozen.
