One Student Mentioned to Another That the Fluidity of a Cell

One student mentioned to another that the fluidity of a cell membrane can be changed by changing the membrane's lipid composition.The second student expressed doubt about this claim.What evidence could the first student find in a research journal to support his claim?

A) A comparison of lipid compositions of membranes in different cells within the same organism
B) An analysis of the change in fatty acid compositions of liver cell membranes in juvenile fish as they mature into adults
C) Results from cell fusion experiments between the same two cells that measure diffusion rates of different membrane proteins
D) Measurement of diffusion rates of the same protein in cell membranes containing different percentages of saturated and unsaturated fatty acids
E) An analysis of the saturated and unsaturated fatty acid content in membranes of skin cells from a single population of cane toads
