RUDIKE [14]
The experimental procedure to test whether plants that are exposed to music grow faster than those that are not should follow the following steps. First, the plants must all be placed in a place where all must be exposed in the same type of environment in terms of sunlight, temperature, water and soil. Second, one of the plant must be exposed to two to three hours of classical music per day. Then you should expose one plant to five to six hours of music per day too. The remaining two plants will be treated as your control plants wherein these will be not exposed to music at all. Before you begin the experiment, you should take pictures of each plant. Next, you should take pictures after two, four and eight weeks. After the steps, observe any visible and palpable differences between the plants which were exposed to music and those that have note. Lastly, also observe the differences between the plants which were exposed to less and those exposed to more music.

PLEASE HELP ME !’
blsea [12.9K]

Answer:

C. Osmosis

Explanation:

Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.

Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.

Osmosis is controlled to a large extent by concentration gradient.

Diffusion on the otherhand is the movement of molecules of a substance from one position to another.

Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.
