​The image shows the Miller-Urey experiment. In their experiment, Miller and Urey used a highly reducing atmosphere with a mixture of hydrogen, ammonia, methane, and water vapor. A mix of precursor molecules mimicking the primordial soup was subjected to substantial amounts of electricity for extended periods, with the samples analyzed after the experiments. The Miller–Urey experiment was proof that the building blocks of life could be synthesized abiotically from gases, and introduced a new prebiotic chemistry framework through which to study the origin of life.
What theory are they trying to prove?
Theory of Spontaneous Generation
Theory of SymbiosisÂ
Theory of Biogenesis
Cell Theory

Which of the following is not included in the classical cell theory?
Who was the first person to see cells under the microscope and give them a name?
Rudolph Virchow's observations helped to disprove was commonly held belief of the time?
How did Zacharias Janssen contribute to the formulation of the cell theory?
Which of these break down macromolecules such as nucleic acids, proteins, and polysaccharides?
Which of the following organelles are not double membrane-bounded?
Which of the following organs are most likely to contain the most mitochondria?
A plant cell is placed in a hypotonic solution, and its vacuole starts to expand. Which of the following cellular structures plays the most important role in preventing the cell from bursting?
The role of the endoplasmic reticulum is crucial in both protein and lipid synthesis. If a cell has a significantly higher amount of smooth ER compared to rough ER, what can you infer about the cell's specialization?
If a eukaryotic cell were missing its nucleolus, what specific impact would this have on cellular functions?
