Galina-37 [17]

Answer:The timing of the cricket's depends on the temperature of the box

so the answer should be

timing of the cricket's chirps

Explanation:Hi!

There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.

The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.

In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.

Therefore, your answer is the third choice, or the timing of the cricket's chirps.

Hope this helped!
