If an animal's internal system determines that there is too much water inside it, how will it likely respond to maintain homeostasis? a. it will expel the excess water as urine. b. it will increase heat production. c. it will constrict bloodflow to the arms and legs. d it will release the hormone glucagon.

A.  It will expel the excess water as urine.

Homeostasis is the natural phenomena which describes the fact that how an organism maintains it's internal environment with respect to the changes that occur externally. The animal's internal system should release the urine in order to expel out excess water inside it. The excretory system of the organism has to work efficiently in order to expel out the water so as to maintain the homeostasis.
