Check all that apply.

Soaps are amphipathic molecules. The dirt particles are nonpolar and are attracted to the hydrocarbon tail of the fatty acid molecule. The hydrocarbon chain is attracted to the water molecules. The carboxylate end of a soap particle interacts with the water molecule. The hydrophobic end of the soap attracts the water molecules surrounding it. The core of a micelle is formed by hydrocarbon chains.
