<em><u>There are three types of scientific investigations: descriptive, comparative, and experimental scenitific investigations.

Explanation:
<span>The growth of plants is regulated
by plant hormones. Some of the major hormones include; auxins, gibberellins,
ethylene, abscisic acid, and cytokinin. Abscisic acid is a stress hormone that
inhibits the growth of seeds during the scarcity of water such as during
winter. Ethylene hormone promotes ripening of fruits. The hormone can exist in gaseous
form and therefore if exposed to unripe fruits can induce ripening. Auxins promote apical growth while gibberellins
promote internodal growth in stems </span>
