The image shows a lipid bilayer, with the polar heads represented by circles and the hydrophobic tails represented by lines. Add the fatty acids into the lipid bilayer to indicate a structure that, when incorporated into a phospholipid, would result in a more fluid membrane with a lower melting point. Be sure to insert the fatty acids into the bilayer in the correct orientation.

Why do the strengths of london (dispersion) forces generally increase with increasing molecular size? choose one: a. heavier atoms have stronger attractions for each other than lighter atoms. b. dispersion forces are all equal in magnitude; there is no size dependence. c. dispersion forces arise from the attraction between the nuclei of atoms, and larger molecules have larger nuclei. d. dispersion forces arise from dipoles caused by the electron distribution being distorted. larger molecules have more electrons and, therefore, more distortions and a bigger force. e. dispersion forces depend on distance. larger molecules are farther apart and so the forces are smaller.
