What do animals do with the carbon dioxide produced in their cells during cellular respiration?a. store it for later useb. reuse it during photosynthesisc. exhale it in the breathing processd. combine it with water to make sugar

below

Explanation:

I'm pretty sure the answer is "exhale it in the breathing process"

Hope this helps! :)

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.
