Answer:
Fish can continue to swim under floating ice on a lake.
Step-by-step explanation:
Water is known to be a unique molecule due to the properties it posseses. According to this question, one of these properties is DENSITY. The hydrogen bonds that holds the molecules of water together makes this possible. Ice, which is the solid state of water, is less dense than liquid water because the hydrogen bonds becomes tightly packed together.
This causes ice to float on liquid water. Hence, in a lake, the less dense feature of ice makes it float on water, causing fishes to continue to swim effectively under floating ice on the lake.
