After what stage does the nucleaus of the parent cell divide into two new nuclei

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.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
