Answer
1: osmosis; 2: partially.
Explanation
This is directly describing the process of osmosis, which is the movement of water molecules from a solution of high water concentration to a solution of low water concentration across a partially permeable (also known as semipermeable) membrane. Diffusion describes the broader process, which also includes the movement of substances across a membrane towards lower concentration, but osmosis is specific to water molecules. An equally important detail is that the movement of these water molecules takes place across a selectively permeable membrane, colloquially referred to as a 'partially permeable membrane.' Hence, we’re dealing here with osmosis—not diffusion—and the membrane is partially permeable—not fully permeable. Therefore, the right phrase fill-ins for spaces (1) and (2) are "osmosis" and "partially," respectively.
