Answer the following question given this paragraph: high proportion of amino acids in the protein have nonpolar side chains. The term hydrophobic interaction is often misused as a synonym for dispersion forces. Hydrophobic interactions arise because water molecules engage in hydrogen bonding with other water molecules (or groups in proteins capable of hydrogen bonding).

Choices: - aquatic bonding - oxygen bonding - helium bonding - hydrogen bonding A:
hydrogen bonding
Answer the following question given this paragraph: Strontium is a silver-colored alkaline Earth metal that is even softer than calcium. Strontium compounds are quite common and have a variety of usesfrom fireworks to cement to toothpaste. In fireworks, strontium compounds produce deep red explosions. In toothpaste, like the one pictured in the Figure below , the compound strontium chloride reduces tooth sensitivity.
