Which of the following is the best example of an emergent property?

• A. Cells are the basic unit of life and all organisms are composed of one or more cells.
• B. Neurons can control which ions they keep inside and outside their membranes.
• C. Cells are made of simple molecules, but when organized together, these molecules can perform living functions.
• D. Molecules can form large chains by joining together multiple atoms.

Answer: (C)

Verified step by step guidance

1. Understand the concept of emergent properties: Emergent properties are characteristics that arise from the interaction and organization of simpler components, which cannot be predicted by examining the individual components alone.
2. Identify the key elements of each option: Analyze each statement to determine if it describes a property that emerges from the organization of simpler parts.
3. Evaluate the first option: 'Cells are the basic unit of life and all organisms are composed of one or more cells.' This statement describes a fundamental biological principle but does not highlight an emergent property.
4. Evaluate the second option: 'Neurons can control which ions they keep inside and outside their membranes.' This describes a specific function of neurons, not an emergent property.
5. Evaluate the third option: 'Cells are made of simple molecules, but when organized together, these molecules can perform living functions.' This statement describes how simple molecules, when organized into cells, exhibit properties of life, which is an example of an emergent property.
