Answer:

Abscisic acid

Explanation:

Abscisic acid (ABA) is a plant hormone, which is produced by plants during stress conditions, such as drought (water-deficit conditions), thus, also known as stress hormone.

In dry conditions, it reduces water loss from plant leaves by reducing the rate of transpiration. ABA causes alteration in the osmotic pressure of stomatal guard cells of leaves. It leads to shrinking and closing of stomata, due to which transpiration is reduced.

Thus, the correct answer is 'abscisic acid.'

DaniilM [7]

Dissolving doe not indicate or guarantee a chemical change.  Most of the time it is a physical change.

Unchanged solid in a liquid does not even indicate any change.

Solid floating on top of liquid does not indicate any change, physical or chemical.

When a mixture creates a new compound (gas from mixing solid and liquid), there is a chemical change.
