Questions: Select the correct answer from each drop-down menu Complete the following sentences to correctly explain how life could have formed on Earth. According to one hypothesis, life on Earth emerged from amino acids in the presence of large amounts of gases seeping from deep-ocean vents. Another hypothesis, called the primordial soup, suggests that the formation of life was due to the effects of in Earth's atmosphere.

To complete the sentences correctly, we need to understand the context of each hypothesis mentioned.

1. The first hypothesis refers to life emerging from amino acids in the presence of gases from deep-ocean vents. This is related to the idea that life could have originated in hydrothermal vent environments, where amino acids and other organic molecules could form and assemble into more complex structures due to the energy and chemical conditions present.

2. The second hypothesis, called the primordial soup, suggests that life formed due to the effects of certain conditions in Earth's atmosphere. This typically refers to the idea that lightning or ultraviolet radiation could have provided the energy needed to synthesize organic molecules from simple inorganic compounds in the early Earth's atmosphere.

Based on this understanding, the correct completions for the sentences are:

1. According to one hypothesis, life on Earth emerged from amino acids forming in the presence of large amounts of gases seeping from deep-ocean vents.

2. Another hypothesis, called the primordial soup, suggests that the formation of life was due to the effects of lightning in Earth's atmosphere.
