Answer:
B) Osmosis of water molecules from unknown solution A likely caused the increase in mass observed.
Explanation:
Osmosis is a type of <em>diffusion </em>(a random movement of molecules to an area of lower concentration from an area of higher concentration) of water. Like other molecules, water can pass through a cell membrane and it will diffuse across the membrane, along its own concentration gradient independent of other particles that could be present in solution. The concentration of water in a solution is <em>inversely </em>(opposite) related to the concentration of the solute, meaning that water will move from a region of high water potential to a region of lower water potential during osmosis.
Unknown solution A had the highest water potential with a sucrose concentration of 0.0 M. This means that water diffused through the membranes of the cells in the sweet potato cube as it moved along its own <em>concentration gradient</em> (from a region of high water potential to a region of lower water potential) causing an increase in the mass of the sweet potato cube
