Summary Introduction
To review:
The modern levels of carbon dioxide and oxygen, as compared to the levels when they first came to exist.
Introduction:
The formation of Earth took place around 4.6 billion years ago. The asteroid impacts were at a peak after the earth’s formation but then started decreasing subsequently. The asteroid impacts ceased to be of consequence around 3.7 billion ago. As the asteroid impact decreased, the level of oxygen (O2) started increasing. The decrease in the impact of asteroid played a crucial role in the origin of life. The plausibility of life increased when the impact of asteroid diminished.

Students have asked these similar questions
Scientist have determined that the early Earth had no free oxygen anywhere. Briefly explain what evidence in
the rock layers that scientists found to prove when the early conditions on earth had free oxygen in the
atmosphere.
The Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and condensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experiment
Around the time Eukaryotic Cells began to compartmentalize their reactions, and the chloroplast
and mitochondria evolved, the atmosphere went through a shift in composition. A new deadly
gas became more and more prominent, which likely caused a mass extinction for those
organisms that couldn't adapt to its toxicity. The gas was:
Nitrogen
Sulfuric Acid
Oxygen
Methane

- Answer the question briefly and explain it(The question is all about History of Life on Earth). Question: What was the Earth like million years ago? Describe.arrow_forwardWhich of the following accurately describes the Hadeon Eon? Earth during the Hadeon Eon closely resembled the earth of today. Earth was extremely hot and molten in nature during the Hadeon Eon. Earth contains an oxygen-rich atmosphere that allows photosynthetic organisms to flourish. Life first appeared on Earth during the Hadeon Eon.arrow_forwardIn Stanley Miller’s experiment to recreate the early Earth conditions that gave rise to life, describe which part of the experimental instruments mimicked the ocean, the atmosphere, rain, and lightning.arrow_forward

- In school, students tend to do a lot of activities, research, and assignments in all subjects. Once the deadline is near, they tend to work UNDER PRESSURE. They get easily mad and complain about everything. Why do you think this thing happen? How will you relate this scenario to the earth's interior that is also under pressure? Answer the following questions, explain your answers by citing your references and evidences (make your answer as brief as possible and underline the key words/ phrases) At present, a significant increase in greenhouse gases and atmospheric temperature is being felt. How will this affect the activities of plants, animals, microorganisms, etc. in terms of photosynthesis? (recall topic on enzymes) If energy is never destroyed, why do we “run out of energy” at the end of a race? Give the different factors that can affect the rate of photosynthesis. How does different light intensities affect the rate of photosynthesis? Why do you think is the coupling…arrow_forwardThe oxygen revolution permanently changed Earth’s environment and dramatically impacted the evolutionary history that followed. Answer ALL the questions related to this phenomenon, below. Give the span of geological timewhen the oxygen revolution occurred. Provide oneline ofevidence for the oxygen revolution. What evolutionary novelty(complex metabolic pathway) enabled these new organisms to release so much O2? Organisms with what kind of metabolismprobably went extinctbecause of the oxygen revolution? What kind of metabolism, not possible before, likely evolved in responseto the oxygen revolution?arrow_forwardThen answer the following questions: 1. Describe one characteristic you see in organism 3 which might have had an advantage over organism 2. 2. How might these fossils provide evidence for evolution?arrow_forward
- Studying the decay of radioactive isotopes in dead organisms helps scientists to identify fossilized remains. The ratio of C-12 to C-14 in the atmosphere is 1 x 1012. The table shows this ratio inside the body of three organisms. Organism C12/C14 Ratio E 8 x 1012 F 1 x 1012 G 4 x 1012 What can most likely be concluded from the above information? Only Organism F is alive, and Organism G died before Organism E. Only Organism F is alive, and Organism E died before Organism G. Only Organism E is alive, and Organism G died before Organism F. Only Organism E is alive, and Organism F died before Organism G.arrow_forwardWhich of the following is the last step in the Oparin-Haldane Model for the beginning of life? a. Membranes form around the first cells b. Simple molecules assembled into building blocks c. Polymers assembled from simple building blocks d.
