C. The average motion of particles and molecules.

B

Explanation:

The temperature of an object, usually measured in degrees-Fahrenheit or degrees-Celsius, tells us how much heat, or energy, the object has.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
