What causes differential growth in stem plant cells? thigmotropy auxins starches elongation

auxins

Explanation:

Auxins are natural plant hormones that act on the plant's cell wall, promoting its distension and, consequently, cell elongation, including plant stem cells. This function promotes the growth of the parts of the plant, causing the elongation of the stem and even the apical dominance that allows the center of the plant's crown to grow more than its sides.

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.
