Grizzy was live in and around puts of Alaska. They love to lorage and fish. What is an important form of prey that adds vail nutrients to their diet?
berries
bulbs
roots
Salmon

I believe the answer is D. salmon

Explanation:

In the question it says "They love to lorage and fish" and something that has nutrients in it are fish, or salmon, so thats how I got the answer.

(Please let me know if I got it wrong so I can edit the 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.
