Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy (although I suppose we wouldn't even exist so it's kind of a moot example).
They grow on bare rock and release acids as parts of thier metabolism.
War bonds are government backed bonds issued when there's a war because wars are expensive and the government fighting the war needs a lot of liquid money very quickly.
Hydrogen bonds are important to the body for several reasons. For one thing, they cause DNA to retain its double helix structure. Additionally, they contribute to the folding of proteins, which is necessary for proper protein function.
"Bonds" do not "have" bonds, because they are bonds themselves. The questioner may have meant to ask, "Molecular compounds have what type of bonds?", and the answer to that question is "covalent bonds".
Hydrogen bonding is responsible to maintain liquid state of fluids including water in living bodies other wise the fluids must be converted in gaseous state and living bodies should be dry or dead.
Atoms or molecules do chemical reactions to be stable, noble gasses are already stable, so they do not react with other molecules to form chemical bonds
Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
Metabolism of food in the body is a chemical change for the same reason as any other chemical change: New chemical bonds are formed and/or chemical bonds existing in the reactants are broken. Both bond breaking and bond formation occur in metabolism.

Biochemistry is the study of chemical substances that come from plants or animals. This is important in the study of how to protect life on our planet.

Cinnamon speeds your metabolism. Also sleeping with a warm pack on your stomach. It is important to get the required amount of sleep for a quick metabolism.
