Study the image of the fossil shown below. how might a scientist use this fossil to learn more about the history of life on earth?

(Lets hope i'm right!)

When they identify the animal, they can see how it has developed and changed over time. They can also identify other things like what they last ate before they died in their poop. Lastly, they can compare and contrast bone structures.

Have a lovely day! ~Pooch ♥

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.
