Question: 1 / 425

Which type of bond is broken by water and heat?

Chemical bond

Disulfide bond

Hydrogen bond

Water and heat can break many types of bonds, including chemical bonds, disulfide bonds, and salt bonds. However, the bond most commonly broken by water and heat is the hydrogen bond.

This is because water is a polar molecule, meaning it has positive and negative regions. When heated, the molecules within water start moving around more, and when in contact with another molecule such as DNA or protein, the positive and negative regions of water can interact with the charged or polar regions of the molecule, weakening or breaking the hydrogen bonds between them.

The other options, chemical, disulfide, and salt bonds, are all stronger types of bonds that require more energy to break and are not easily broken by water and heat. Therefore, they are not the correct answer to this question.
