In a field of sunflowers, there are varying heights. a plant breeder is determined to breed out all of the extremely tall and extremely short plants. his goal is to create a population of sunflowers that are all of average height. in terms of natural selection, we would call this selection.
a) directional
b) disruptive
c) stabilizing
d) suggestive

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.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
