When two solutions are separated by the membrane through which water can pass but starch cannot, the osmosis will occur.
Osmosis is described as the spontaneous movement of water through membrane from a region of lower solute concentration into a region of higher solute concentration. Water movement tends to equalize the solute concentrations on the two sides.
Experimental Setup In this section you describe how the experiment was done and summarize the data taken. One typically describes the instruments and detectors used in this section.
This figure illustrates 3 hypotheses of how a cancer stem cell may arise: (1) A stem cell undergoes a mutation, (2) A progenitor cell undergoes two or more mutations, or (3) A fully differentiated cell undergoes several mutations that drive it back to a stem-like state.
Answer:
2nd one
