Scenario:Imagine you are observing Paramecium, a single-celled freshwater organism, under a microscope. You notice that small vacuoles repeatedly fill with water and then collapse, expelling the water out of the cell. Your instructor explains that without this process, the Paramecium could face serious problems. Question:What is the primary significance of these contractile vacuoles in Paramecium? A. They help the cell store extra water for photosynthesis.B. They prevent the cell from taking in too many nutrients from its surroundings.C. They maintain the balance of water inside the cell, preventing it from bursting.D. They allow the cell to remove toxins produced during respiration.

    Scenario:A medical researcher is studying the effect of different intravenous (IV) fluids on red blood cells (RBCs). During the experiment, she places RBCs in two solutions: Solution A: After some time, the cells appear shriveled and spiky under the microscope. Solution B: The cells swell considerably, and some rupture, releasing their contents. The researcher explains that the solutions used caused changes in water movement across the cell membranes. Question:Which terms correctly describe what happens to the RBCs in Solution A and Solution B, and what type of solutions caused these effects? A. In Solution A, the RBCs crenate due to a hypertonic solution; in Solution B, they lyse due to a hypotonic solution.B. In Solution A, the RBCs lyse due to a hypotonic solution; in Solution B, they crenate due to a hypertonic solution.C. In Solution A, the RBCs lyse due to a hypertonic solution; in Solution B, they crenate due to a hypotonic solution.D. In Solution A, the RBCs become isotonic, leading to crenation; in Solution B, the RBCs lyse because both solutions were isotonic.
