Besides the exchange of oxygen and carbon dioxide with the environment, an important role of the respiratory tract is, during inspiration, to heat the air to body temperature and to saturate it with water, before it reaches the alveoli. This is physiologically crucial because it protects the alv...
Oxygen uptake and carbon dioxide release at 28°C were determined in worker castes of twenty-six species of forest termites from the Danum Valley Conservation Area, south-east Sabah, by Warburg manometry. Metabolic rate varied inversely with body weight in a suite of soil-, wood/soil- and ...
The Tair, DO, and PAR showed significant seasonal and spatial differences (P < 0.001). As expected, air temperature (Tair) decreased from 35.1 °C ± 2.6 °C in summer to 21.8 °C ± 4.5 °C in winter. On the contrary, the water dissolved oxygen (DO) ...
FEW, if any, really simple methods have been proposed for the simultaneous estimation of the carbon dioxide evolution and oxygen uptake of living tissues in which it is possible to maintain the composition of the gas mixture surrounding the tissue constant, and at the same time detect a rapid ...
3. A method according to claims 1 or 2, characterized in that the oxygen and the carbon dioxide contents of the gas in the container (5) are measured. 4. A method according to any of the claims 1-3 above, characterized in that the volume of the gas in the container (5) is calcu...
Plants need a continuous supply of important gas called oxygen to perform a crucial process called photosynthesis. Plants play a significant role in balancing the concentration of vital gases in the atmosphere.Answer and Explanation: Osmosis is responsible for many physiological processes taking pla...
SOM specific heterotrophic respiration was lower in wet than in dry areas, while no such dependencies were found for chamber-based soil CO2 fluxes, implying that oxygen depletion resulted in lower SOM reactivity. The chamber-based soil CH4 flux differed significantly between the wet and dry areas....
For all gases except carbon dioxide, nitrogen, and oxygen the concentration of the gas was below the limits of detection of the instrument, for each biosolid type, over the hour. For methane this was <0.1%, for hydrogen <20 ppm, and for ethylene, ethane, and acetylene <5 ppm. The...
Oxygen uptake and carbon dioxide release at 28°C were determined in worker castes of twenty-six species of forest termites from the Danum Valley Conservation Area, south-east Sabah, by Warburg manometry. Metabolic rate varied inversely with body weight in a sui...
He left his indelible mark on the dark reactions of CAM with the words "The positive contribution made by the Leipzig workers was to draw attention to the possible cardinal importance (cf. Gustafson's qualified statement) of carbon dioxide rather than oxygen in controlling diurnal fluctuations in...
