The picture shows an experimental set up for the process of osmosis. the potato has a cavity on top, as shown in the picture. some sugar solution is poured into the cavity and the potato is placed in a beaker of water. after some time, it is observed that there is a rise in the level of liquid in the cavity. this confirms that

The correct answer would be 

A) Water from the beaker has moved into the cavity.

Answer;

A) Water from the beaker has moved into the cavity.

Explanation;Osmosis is a physiological process which involves the movement of water molecules from a region where there are highly concentrated to a region where they are lowly concentrated through a semipermeable membrane.In the experiment water molecules moved from the beaker where they are highly concentrated to the cavity where they are lowly concentrated. Sugar solution is a hypertonic solution while the water in the beaker is hypotonic therefore water moves osmotically from the beaker through the potato to the cavity.

The correct answer is a. we know this because n (hap) + n (hap) = 2n (dip).

Except hold on to his or her beliefs even if there is no evidence for those beliefs.
