Which of the following properties of water molecules has important implications for life?

• A. High heat capacity
• B. Low surface tension
• C. Inability to dissolve polar substances
• D. Non-polar nature

Answer: (A)

Verified step by step guidance

1. Begin by understanding the concept of 'high heat capacity'. Water's high heat capacity means it can absorb a lot of heat before its temperature changes significantly. This property is crucial for maintaining stable temperatures in environments, which is vital for life.
2. Next, consider the concept of 'surface tension'. Water actually has high surface tension, not low. This is due to the hydrogen bonding between water molecules, allowing it to support small objects and organisms on its surface.
3. Explore the ability of water to dissolve substances. Water is known as the 'universal solvent' because it can dissolve many polar substances due to its polar nature, which is essential for biochemical reactions in living organisms.
4. Understand the polarity of water molecules. Water is polar, not non-polar. This polarity allows it to form hydrogen bonds, which are critical for many biological processes, including the structure of DNA and proteins.
5. Finally, evaluate each property in terms of its biological significance. High heat capacity, high surface tension, ability to dissolve polar substances, and polar nature are all properties of water that have important implications for life, unlike the incorrect options provided.
