It is clearly shown in the last column that, as the concentration of ammonia nitrogen rises, the number of larvae falls.
This also appeared to be closely related to ammonia nitrogen.
They found evidence of ammonia emanating from the tick faeces.
Furthermore, molecules such as ammonia could conceivably replace water in its function as a universal solvent in a biological system.
Whatever the value, none could have been pleasant to handle or to have aboard ship, but those containing the most ammonia were the most foul-smelling.
This includes, in particular, polar solvents like ammonia, hydrocyanic acid, and methanol, and possibly non-polar compounds such as methane and ethane.
The plates were removed and ammonia eliminated in an air-stream overnight.
The results obtained in this case were precisely similar to those obtained with ammonia.
