Coyote pups have a higher chance of survival than other species why is it true

Explanation:

Because the parents are clever and they are united in the protection of the young. Also coyotes travel in packs and the other adults help out. The non alphas regard the pups of the alpha pair as their own and guard them as though that was true.

Coyotes are very interesting to read about, and I recommend you do it. Throughout the years I've read a great deal about Coyotes and I admire them immensely. Other people are not so generous in the appraisal.

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.
