Mice on Ice!

Today in lab we explored how external stimuli such as changes in temperature (in our case cold) requires organisms to respond to restore homeostasis.

As the temperature changed (got colder) the mice had to do more cellular work (why? what is happening?) to maintain a constant body temperature. So if more cellular work is required, then more ATP must be made.  What process contributes the energy needed for ATP formation?

As such what happens to the mouse's breathing rate?

We talked about the respiratory system as well and demonstrated the diaphragm and how it moves in relation to inhalation and exhalation.
