    animal though? In this experiment we are using lab mice‚ Mus musculus‚ to see if the introduction of a predator scent (fox urine) increases‚ decreases‚ or has no effect on the metabolic rate within them. We will calculate the mass specific metabolic rate and use a t-test to determine if there is a significant change in metabolic rate when the mouse is exposed to the predator urine and when it is not exposed. With these mice being born and raised in a lab‚ the fox urine should have no effect on the metabolic
