What is one similarity between the lungs and capillaries? a-They are both activated by inhalation.
b-They are both involved in gas exchanges.
c-They are both part of the circulatory system.
d-They are both regulated by the heart.

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.
