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."
The correct blanks are:
1. Alexander Oparin's and J. B. S. Haldane's
2. Methane

What is the experiment of Alexander Oparin?Miller and Urey executed experiments to support the “Alexander Oparin's and J. B. S. Haldane's” hypothesis.
In their experiment, they mixed “Methane (CH4),” ammonia, hydrogen gas, and water in a blocked system and “Simulate” it to mimic conditions on early Earth.
After stimulating the system with a “Sparkling device” to mimic “Lightning Storm,” they found 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.”

Two students are talking about what causes the tides. Student A says that the tide comes in and goes out based on differences in the height of the sea level. Student B says that the changing tides are caused by Earth rotating into and out of the tidal bulges. Discuss the explanations of the tides by both Student A and Student B. Which explanation is more technically correct
Answer:
Student A is more technically correct
Explanation:
According to student A ; the tide is caused by the difference in the height of the sea level, while
According to Student B the changing tides are caused by the earth rotating in and out of the tidal bulges.
while the General cause of Tides is defined as
The daily rise and fall of tide is caused by the gravitational pull of the sun and moon, and the various heights of the sea at any time of the day represents the rise or fall of tides
hence student A is technically correct.
