Question

7 multiple choice 1 point in an aqueous environment, the phospholipids of a membrane ____. are arranged in a bilayer with the polar heads of each layer located at the membrane surface are arranged in a bilayer but the phospholipids have no specific orientation dissociate into their lipid and protein components are arranged in a bilayer with the fatty acid tails located at the membrane surface are arranged in a single layer

Explanation:

Phospholipids are amphipathic (polar heads, nonpolar tails). In aqueous environments, they form a bilayer: polar heads face water (membrane surface), nonpolar tails face inward (away from water). This structure is stable and specific.

Answer:

A. are arranged in a bilayer with the polar heads of each layer located at the membrane surface
