Answer

Brief Explanations:

Cell membranes are dynamic structures. Their properties change based on the types and proportions of molecules (like lipids, proteins) that make them up. Membrane fluidity is influenced by factors such as the length and saturation of phospholipid fatty - acid tails (more unsaturated and shorter tails increase fluidity). Cholesterol has a dual - effect on membrane fluidity. At high temperatures, it decreases fluidity by restricting phospholipid movement, and at low temperatures, it increases fluidity by preventing phospholipids from packing too tightly. However, the idea that cell membrane properties are constant and unchanging is incorrect as cells can modify their membrane composition in response to environmental changes (e.g., temperature changes, nutrient availability).

Answer:

cell membrane's property remains constant and univariable
