Plant hormones: how do plant hormones affect plant growth and development? seeds do not usually sprout in the winter—how do they know when to germinate? grocery stores need to have ripe, unbruised produce to sell to the public, but often this produce is packed weeks ahead of time and shipped hundreds of miles to get to the store. how does it ripen after harvest? there are several different plant hormones that to orchestrate plant growth, development, ripening, and responses to various environmental stimuli.

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

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
