Final answer:
The option not including the active transport mechanisms for ion and water movement would lack a key feature of transport epithelia and thus not be associated with a typical transport epithelium used for ion and water balance.
Step-by-step explanation:
The option that would not have the 5 features associated with a transport epithelium used for ion and water balance is d. Lack of active transport mechanisms for ion and water movement. Transport epithelia often include structural features that allow the selective transport of molecules and ions across their cell membranes. These features generally include a simple structure with few cell layers to enable efficient transport, a high surface area with microvilli or other modifications to increase the surface for absorption or secretion, and tight junctions between cells to prevent leakage of solutes and maintain a directional movement of substances. Active transport is a crucial feature of transport epithelium, enabling the cell to move ions against their concentration gradient, which is necessary for maintaining ion and water balance within tissues and organs.
