A teacher cut an apple into three wedges of the same size. She dipped one wedge in lemon juice, dipped another in water, and left one alone. Then she left the wedges on a paper towel on her desk. After 1 hour, only the wedge that had been dipped in lemon juice was still yellow. The other two wedges had turned brown. What is the responding variable in this experiment? O A. The color of the apple wedges after 1 hour B. The size of the apple wedges C. The lemon juice applied to one of the apple wedges D. The liquid the apple wedges were dipped in

Its A

Explanation:

Had to guess on apex The answers is A. The color of the apple wedges after 1 hour

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.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
