PROBLEM: Passage: An anticline is a fold that arches upward. The rocks dip away from the center of the fold ( Figure below ). The oldest rocks are found at the center of an anticline. The youngest rocks are draped over them at the top of the structure. When upward folding rocks form a circular structure, that structure is called a dome . If the top of the dome is eroded off, the oldest rocks are exposed at the center. Answer: anticline

Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Answer: an organelle

SOLUTION: Any structure inside a cell that is enclosed by a membrane is called?
