Answer 2

Answer:

In cold regions, aquatic animals can survive at a temperature of 4°C. Because (1) Ice floating in water is an Insulator, (2) The heat of water under ice cannot go into the atmosphere, (3) The Anomalous behaviour of water, All these parameters are consisted in this phenomenon.

Correct answer is - (4) All of the above options.

Explanation:

• Water has a unique property in that it has its maximum density at around 4 degrees Celsius. The density decreases as we go above or below the mark. In addition, ice has a lower density than water. Thus, a circulation system is established until the water in the pond reaches its maximum density of 4 degrees Celsius.

                                                     ↓

• When the temperature in the atmosphere reaches 0 degrees Celsius, ice begins to form in ponds, forming a layer on top with water beneath it. If water did not have this property, aquatic life would be unable to exist in bodies of water during cold seasons.

                                                     ↓

• After a sufficient layer of ice has formed, it prevents further heat loss from the bottom layers of water. This is why fish and other aquatic animals and plants can survive in ponds and other bodies of water even when the temperature outside reaches or falls well below zero degrees.

⇒  Therefore the correct answer is (4) All of the above options.
