Question

multiple choice question
which best describes how water helps to regulate body temperature?
o its covalent bonds hold its atoms tightly together
o its covalent bonds give it the property of being hydrophobic
o its hydrogen bonds help water to dissolve many kinds of solutes
o its hydrogen bonds counteract the increased movement of molecules

Explanation:

Water has hydrogen - bonding. When body temperature rises, the increased kinetic energy of water molecules is counteracted by hydrogen bonds as they break and absorb heat. When body temperature drops, hydrogen bonds form and release heat. Covalent bonds are not related to temperature regulation in this context, and water is hydrophilic not hydrophobic. The ability to dissolve solutes is not directly related to temperature regulation.

Answer:

its hydrogen bonds counteract the increased movement of molecules
