The two tectonic plates slide past eachother
Tundras and deserts have a number of similarities such as their lack of water or how organisms that inhabit them are have special features to survive their extreme weather. Both are nearly unsustainable for human life and have just like the tundra, deserts have freezing temperatures at night.
Homo ergaster may have been the first human species to leave Africa and fossil remains show this species had expanded its range into southern Eurasia by 1.75 million years ago. Their descendents, Homo erectus, then spread eastward and were established in South East Asia by at least 1.6 million years ago.Oct 30, 2015
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."
