THE SULFUR-OXIDIZING PROKARYOTES. Biological oxidation of hydrogen sulfide to sulfate is one of the major reactions of the global sulfur cycle. Reduced inorganic sulfur compounds (referred to below as sulfur) are exclusively oxidized by prokaryotes, and sulfate is the major oxidation product. Sulfur oxidation in members of theEukarya is mediated by lithoautotrophic bacterial endosymbionts (44).
In simpler terms: the dew point, or frost point, is the temperature at which dew or frost will form should the air temperature fall sufficiently. Other things being equal, as the temperature falls, the relative humidity rises, reaching 100% at the dew point, at least at ground level.ew point temperature is never greater than the air temperature, since the relative humidity cannot exceed 100%.
If so... Relative humidity is exactly that: it is relative to the temperature. â¦ Warmer air can hold more moisture than cooler air, so if warm air is 40% humid, and cool air is 40% humid, then the warmer air is actually more humid than the cooler air, even though the RELATIVE humidity is the same. Specific humidity is expressed in GPP, or Grains [of water] Per Pound [of air].
