Question 31 Chemically, these are triacylglycerols, triesters of glycerol with three long- chain carboxylic acids. A. waxes B. fats and oils C. fatty acids D. soaps Question 32 When soaps disperse in water, the long hydrocarbon tails cluster together in a hydrophobic ball, while the ionic heads on the surface of the cluster stick out into the water. These spherical clusters are called: A. fatty acid esters B. triacylglycerols C. lipid bilayers D. micelles Question 33 DNA can best be described as A. two backbones of alternating deoxyribose and nitrogenous base on the exterior, with phosphates on the interior B. two backbones of alternating deoxyribose and nitrogenous base on the interior, with phosphates on the exterior C. two backbones of alternating deoxyribose and phosphate on the exterior, with nitrogenous bases on the interior D. two backbones of alternating deoxyribose and phosphate on the interior, with nitrogenous bases on the exterior E. two backbones of alternating nitrogenous base and phosphate on the exterior, with deoxyriboses on the interior
