Respiration animal types

Knowing the results of epidemiology studies on the association between diesel exhaust exposure and lung cancer, and animal studies on the toxicity of two types of soot, what can we conclude concerning the toxicity to humans of soot associated with fires Combustion processes produce small, respirable size soot particles. The composition of the soot from fires can vary widely with the condi-... 

The anaerobic respiration that lakes place in the muscles of higher animals, when insufficient oxygen is available for a complete breakdown of lhe lond. is also called fermentation. Lactic acid and carbon dioxide are the products of this type of fermentation. 

The quantity of litter input provides the second critical link between NPP and decomposition because NPP governs the quantity of organic matter inputs to decomposers. When biomes are compared at steady state, heterotrophic respiration (i.e., the carbon released by processing of dead plant material by decomposer organisms and animals) is approximately equal to NPP. In other words, net ecosystem production (NEP), the rate of net carbon sequestration, is approximately zero at steady state, regardless of climate or ecosystem type. This indicates that the quantity and quality of organic matter inputs to soils, as determined by... 

Carbon Dioxide, Carbonic acid gas carbonic an -hydride. COji mol wt 44.01. C 27.29%, O 72.71 % Occurs in the atms of many planets. In our solar system, e.g., on Venus, the optical layer thickness due to COj is 100,000 cm/atm, but only 220 cm/atm on Earth. Analyses of air in the temperate zones of the Earth show 0.027 to 0.036% (v/ v) of COj G. P.
