Sodium hydroxide absorbs all CO 2 from the air in the apparatus from the beginning. Potassium hydroxide could be used instead of sodium hydroxide. They both absorb CO 2. As the germinating seeds use oxygen and the pressure reduces in tube A so the manometer level nearest to the seeds rises. greenscape services bluffton scWebRespirometry is a general term that encompasses a number of techniques for obtaining estimates of the rates of metabolism of vertebrates, invertebrates, plants, tissues, cells, or microorganisms via an indirect measure of heat production ( calorimetry ). greenscapes design softwareWebThe respirometer is immersed in water bath to prevent temperature affecting the pressure and hence volume of air in the apparatus. But if one is testing impact of temperature the water bath temperature could be adjusted.
