Write a paragraph that describes the path that one drop of water takes as it moves through the water cycle. in your paragraph, include at least two changes in the form of water.

chordata is the answer

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.
