Question

multiple-choice question
where do we think organic monomers came from?
the earths core
we dont know
asteroids and meteors
animals
rewatch

Explanation:

To determine the origin of organic monomers, we analyze each option:

• "the earth's core" is incorrect as the core is metallic and not a source of organic monomers.
• "we don't know" is inaccurate because there is scientific evidence supporting the idea that organic monomers (like amino acids) could have been delivered to Earth by asteroids and meteors (e.g., analysis of meteorites showing organic compounds).
• "animals" is incorrect because animals are made of organic polymers and monomers, but they are not the source of the initial organic monomers on Earth (life had to originate from pre - biotic sources).
• "asteroids and meteors" is correct. Scientific research, including the study of meteorites, has shown that these celestial bodies can carry organic compounds (monomers) that could have contributed to the pre - biotic chemistry on Earth.

Answer:

C. asteroids and meteors
