Final answer:
In a Venn diagram comparing active transport and passive transport, the label that belongs in the region marked 'x' is 'uses energy'.
Step-by-step explanation:
In a Venn diagram comparing active transport and passive transport, the label that belongs in the region marked 'x' is uses energy. Active transport is the process by which cells move molecules across the cell membrane against the concentration gradient, and it requires energy in the form of ATP. On the other hand, passive transport is the movement of molecules across the cell membrane with the concentration gradient, and it does not require energy.
