Cataracts, the medical condition where the lens of the eye becomes cloudy, are a leading cause of blindness. describe how developing a cataract would change the path of light through the eye.

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.

nucleus

would be most reasonable answer tbh
