They po it out when it is digested
The right answer is to measure the amount of released carbon dioxide.
The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.
A is false because glucose is not found in the urine, except in the case of diabetes mellitus.
C is false because the consumption of calories does not mean that we will directly use it.
D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
Temperature is a quantitative measurement because it can be "measured". Quantitative data is where you record data that is measurable. Qualitative data is research collected from observations.
