TASK DEFINITION: Given a scientific passage and an answer, generate a question for the given answer.
PROBLEM: Passage: In addition to having a plasma membrane, cytoplasm, a nucleus and ribosomes, eukaryotic cells also contain membrane-bound organelles . Each organelle in a eukaryote has a distinct function. Because of their complex level of organization, eukaryotic cells can carry out many more functions than prokaryotic cells. The main differences between prokaryotic and eukaryotic cells are shown in Figure below and listed in Table below . Keep in mind that some eukaryotic cells may have characteristics or features that other eukaryotic cells lack, such as the cell wall. Answer: eukaryotic cells

SOLUTION: Which type of cell can carry out more functions, eukaryotic cells or prokaryotic cells?

PROBLEM: Passage: A front forms at the boundary between two air masses. Types of fronts include cold, warm, occluded, and stationary fronts. Clouds, precipitation, and storms commonly occur along fronts. Answer: a front

SOLUTION: What forms at the boundary between two air masses?

PROBLEM: Passage: The molarity is 0.0129 M, the molality is 0.0129 m, the mole fraction is 2.33 10 , and the solution contains 1830 ppm Na2HPO4. Mole fraction is most useful for calculating vapor pressure, because Raoult's law states that the vapor pressure of a solution containing a non-volatile solute is equal to the mole fraction of solvent times the vapor pressure of the pure solvent. The mole fraction of the solvent is just one minus the mole fraction of solute. Answer: solute

SOLUTION:
The mole fraction of the solvent is just one minus the mole fraction of what?
