What is the respiratory quotient and how would you measure it for a small animal like a gecko?

Respiratory quotient is calculated as the fraction of the concentration or amount of carbon dioxide released to the amount or concentration of oxygen consumed or utilized.

RQ shows the amount of carbohydrate, fat or protein involved for the metabolic use in the body. Respiratory quotient in living organism even in smaller organisms are measured by an instrument called as respirometer.

the correct answer in apex is tissue development, i know because i just had this question

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
