Scientists have discovered and identified only a fraction of the species living and extinct. True or False?

Science

This is true because humans can only know so much due to unexplored lands, water depth, and evidence of extinction being hidden.

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.
