The correct answer is: (1) and (2) are true and (2) explains (1)
 
Here's the explanation:
  • Aquatic life in polar regions: In the polar regions, the surface water of lakes, rivers, and oceans often freezes, forming a layer of ice. This ice serves as an insulator, preventing the water beneath the ice from freezing and maintaining a stable temperature for aquatic life to survive.
  • High latent heat of fusion: Water has a high latent heat of fusion, which means it takes a large amount of energy to change its state from solid (ice) to liquid (water) or vice versa. The ice layer in the polar regions acts as a barrier, keeping the heat of the water below it from escaping into the cold atmosphere. This helps to maintain the temperature of the water, ensuring the survival of aquatic life.
  • Connection between (1) and (2): The survival of aquatic life in polar regions is supported by the unique properties of water, such as its high latent heat of fusion. The ice layer prevents heat from escaping, maintaining a stable temperature in the water beneath it. Thus, statement (2) explains the reason behind the safety of aquatic life in polar regions as mentioned in statement (1).
