which statement is true of eukaryotes but not of prokaryotes?
○ they must contain a nucleus.
○ they do not have membrane-bound organelles.
○ they must be multicellular.
○ they are always single-celled.

Explanation:

Eukaryotes are defined by having a membrane-bound nucleus, while prokaryotes lack this structure. The other options are incorrect: eukaryotes have membrane-bound organelles (opposite of the second option), can be unicellular (e.g., yeast) so are not always multicellular, and prokaryotes are typically single-celled (so the fourth option is false for eukaryotes).

Answer:

They must contain a nucleus.
