What is the term used to estimate energy expenditure by measuring the amount of body heat released by a person?Multiple choice question.Estimated heat releaseIndirect calorimetryDirect calorimetryEstimated energy requirement

Direct calorimetry works because approximately ____% of the energy the body uses, eventually leaves as heat.Multiple choice question.60408020

What unit is used to measure energy when calculating specific heat capacity? Give the abbreviation, not the full name.

Indirect calorimetry calculates heat that living organisms produce by measuring either their production of carbon dioxide and nitrogen waste (frequently ammonia in aquatic organisms, or urea in terrestrial ones), or from their consumption of oxygen. Lavoisier noted in 1780 that heat production can be predicted from oxygen consumption this way, using multiple regression. The dynamic energy budget theory explains why this procedure is correct. Heat generated by living organisms may also be measured by direct calorimetry, in which the entire organism is placed inside the calorimeter for the measurement.A widely used modern instrument is the differential scanning calorimeter, a device which allows thermal data to be obtained on small amounts of material. It involves heating the sample at a controlled rate and recording the heat flow either into or from the specimen.
