Answer

Brief Explanations:

Cell - membrane fluidity is affected by various factors. Cholesterol acts as a fluidity buffer. A decrease in cholesterol concentration reduces the ability of cholesterol to maintain membrane fluidity, making the membrane less fluid. An increase in temperature increases fluidity. Unsaturated fatty - acid tails increase fluidity due to kinks preventing tight packing, while saturated fatty - acid tails decrease fluidity as they pack tightly. Tight junctions are related to cell - to - cell adhesion and not directly to membrane fluidity.

Answer:

a decrease in the cholesterol concentration
