Quick comprehension check
“Potato slices were placed in two different salt solutions, A and B. After 30 minutes, the potato slices in solution A gained mass, while the potato slices in solution B lost mass. State a claim about the direction of water movement in each solution and identify the evidence that supports your claim. A scientist measures the initial and final volumes of cells placed in a sugar solution. The data shows that the cells' volume increased by 15%. Formulate a claim about the concentration of the sugar solution relative to the cells and identify the evidence that supports your claim. ”
