Multiple Choice

Which of the following statements best describes how continental drift and global climate change have influenced the diversity of organic compounds in living organisms?

They have resulted in the uniform distribution of organic compounds across all continents.

These phenomena have caused the evolution and diversification of organic compounds in response to changing environments.

Continental drift and climate change have had no impact on the diversity of organic compounds.

Continental drift and climate change have led to the extinction of all organic compounds.

Verified step by step guidance

Begin by understanding the concept of continental drift, which refers to the movement of Earth's continents over geological time. This movement can lead to changes in climate, habitat, and the distribution of species.

Consider how global climate change impacts living organisms. Climate change can alter habitats, food availability, and environmental conditions, prompting organisms to adapt or evolve.

Recognize that both continental drift and climate change create new environmental pressures and opportunities, leading to the evolution and diversification of organic compounds in organisms as they adapt to new conditions.

Evaluate the statement options: The uniform distribution of organic compounds is unlikely due to varied environments across continents. Extinction of all organic compounds is not supported by evidence, as life continues to adapt and evolve.

Conclude that the correct statement is that continental drift and climate change have caused the evolution and diversification of organic compounds in response to changing environments, reflecting the dynamic nature of life on Earth.
