Question

what property of water allows insects to walk on its surface?
high specific heat
versatility as a solvent
cohesive behavior
expansion upon freezing
which of the following best explains how waters ability to moderate temperature benefits aquatic life?
it dissolves essential nutrients, making them readily available.
it prevents rapid changes in water temperature, providing a stable environment.
it facilitates the transport of oxygen throughout the water.
it allows ice to float, insulating the water below.

Explanation:

For the first question, water's cohesive behavior creates surface tension, enabling insects to walk on water. High specific heat relates to temperature - change resistance, solvent - versatility is about dissolving substances, and expansion - upon - freezing is about ice density.
For the second question, water's high specific heat allows it to absorb or release a large amount of heat without a rapid temperature change, providing a stable environment for aquatic life. Dissolving nutrients, oxygen transport, and ice - floating are not related to temperature moderation.

Answer:

First question: C. Cohesive behavior
Second question: It prevents rapid changes in water temperature, providing a stable environment.
