To check your answer, let's understand what osmosis is and then analyze each option.
Osmosis is a process that involves the movement of water across a selectively permeable membrane, from an area of lower solute concentration to an area of higher solute concentration. It occurs to balance out the concentration of solutes on both sides of the membrane.
Now let's analyze each option:
A. A cube of sugar dissolving in coffee: This process is actually a form of diffusion, where solute particles (sugar) spread out and distribute evenly in a solvent (coffee). It does not involve osmosis, as osmosis specifically refers to the movement of water.
B. Particles of oxygen filling the lungs: This process is also a form of diffusion, where oxygen molecules move from an area of higher concentration (in the air) to an area of lower concentration (in the lungs). Again, it does not involve osmosis.
C. Water moving across the cell membrane: This option is correct. Osmosis occurs when water molecules move across the cell membrane from an area of lower solute concentration to an area of higher solute concentration in order to equalize the concentration on both sides of the membrane.
D. Transport of proteins from the endoplasmic reticulum to the Golgi apparatus: This process is known as protein transport and involves the movement of proteins within a cell. It does not involve osmosis.
Based on the explanations above, your answer C is indeed correct. Water moving across the cell membrane is achieved through osmosis. Well done!
