Need some help with bio homework

One problem is that the bike doesn’t have the chain.

You can solve the problem by adding a chain.

A source the student can use is asking a mechanic.

Another way is asking her father or neighbors.

Explanation: I hope this helped.

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.
