Respuesta :
The correct answer would be the third choice. One hypothesis regarding the origin of life is “organic molecules from outer space”. Under this concept, it is believed that organic compounds might have come on earth through meteorites. Then these organic compounds were used as the precursors of the living cells. Certain pieces of evidence are also found to support this concept. For example, scientists have experimentally proved that conditions like low temperature and high UV radiations (similar conditions as exist in outer space) can cause the production of organic molecules from simple chemical precursors as present in space. In addition, some organic compounds have also been found in space or other star systems.
Answer:
Scientists think that meteorites can get chemicals such as isopropyl cyanide from a space cloud. So, it’s possible that a meteor that had acquired isopropyl cyanide struck Earth and brought life to the planet.
