A
NA/K Pump
B
Water moving though the cell membrane
C
Kidneys
D
Photosynthesis
Explanation: 

Detailed explanation-1: -Osmosis is the movement of liquid molecules from a higher concentration to a lower concentration through a partially permeable membrane. An example of osmosis can be the intake of water molecules through the root hairs present inside the soil.

Detailed explanation-2: -Examples of Osmosis Osmosis is how plants are able to absorb water from soil. The roots of the plant have a higher solute concentration than the surrounding soil, so water flows into the roots. In plants, guard cells are also affected by osmosis.

Detailed explanation-3: -Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

Detailed explanation-4: -When you keep raisin in water and the raisin gets puffed. When we are suffering from severe sore throat we are advised to gargle salt water.
