Select the pair of structures that best shows how plant cells are different from animal cells

there is no diagram maybe let me know when you have a diagram

B. chloroplasts and cell walls is your 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.

i believe the answer would be b. hope it : )
