A bacterial cell is suddenly expelled from a warm human intestine into the cold world outside. Which one of the following adjustments might the cell make to maintain the same level of membrane fluidity that the cell had in the intestine?a. increase the length of the hydrocarbon tails in its membrane phospholipids.
b. increase the proportion of unsaturated hydrocarbon tails in its membrane phospholipids.
c. increase the proportion of hydrocarbon tails with no double bonds in its membrane phospholipid.
d. decrease the amount of cholesterol in the membrane.

Composed of a phospholipid bilayer with installed proteins, the plasma layer is specifically penetrable to particles and natural atoms and directs the development of substances all through cells. Plasma films must be truly adaptable so as to permit certain cells, for example, red platelets and white platelets, to change shape as they go through restricted vessels.
The plasma membrane additionally assumes a job in securing the cytoskeleton to give shape to the phone, and in joining to the extracellular grid and different cells to help bunch cells together to frame tissues. The layer likewise keeps up the cell potential
Hence the right answer is option b "increase the proportion of unsaturated hydrocarbon tails in its membrane phospholipids"
