Five dialysis bags, constructed of a type of membrane that is permeable to water and impermeable to sucrose, were filled with various concentrations of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose solution. At 10-minute intervals, the bags were weighed, and the percent change in mass of each bag was graphed. Osmosis bag.pngWhich line in the graph represents the bag that contained a solution isotonic to the 0.6 M solution at the beginning of the experiment?

Which of the following is a characteristic feature of anabolic pathways?

Which of the following statements best summarizes an important consequence of the first law of thermodynamics for living organisms?

Which of the following is the most appropriate technique for observing the three-dimensional structure and organization of microvilli on an intestinal cell? [Hint: which tool allows to study the smallest things on the surface of the cell?]

At 10-minute intervals, the bags were weighed, and the percent change in mass of each bag was graphed. Osmosis bag.pngWhich line or lines in the graph represent(s) bags that contain a solution that is still hypertonic to the solution in the beaker at 50 minutes?

Which of the following processes generates a proton-motive force in mitochondria?

Which of the following processes occurs in the Calvin cycle?

Which of the following statements best explains the ability of C4 plants to perform photosynthesis with no apparent photorespiration?

Which of the following is not an immediate net product of the typical mitochondrial electron transport chain?
