Evolution
Explanation:
Evolution – change over time. It is the process by which modern organisms have descended from ancient organisms. Current scientific facts, observations and hypotheses all combine to create current evolutionary theory – which is a well-supported, testable explanation of the biological diversity on Earth.
Phase 1 of the creation of life on earth was that life on earth was from nothing. Small molecules were formed from atoms of carbon and hydrogen. Earth does not have any oxygen rather it contains CO2, methane, nitrogen, hydrogen and ammonia where they were from the eruptions of volcanoes.
C. Because pure water might cause the patients blood cells to burst- because water will move in to the cells down the concentration gradient by osmosis
