Animals take up oxygen and complex oxidizable compounds made by plants, release largely as combustion products carbonic acid and water, partly as simpler reduced compounds, thus using a certain amount of chemical potential energy to produce heat and mechanical forces. Since the latter represent a r...

The mass gain during absorption was measured at regular intervals using a Shimadzu AUW220D electronic balance without buoyancy correction. Each solution was examined three times, and the average value of mass gain was taken for calculation. In order to take into account the weight loss associated ...
