Metamorphosis in amphibians is regulated by thyroxine concentration in the blood, which stimulates metamorphosis, and prolactin, which counteracts thyroxine's effect.

A few days later, the tail is reabsorbed, due to the higher thyroxine concentration required for this to take place.

The reason why pHs of acids are less than 7 is that the concentration of hydronium ions is greater than 10 < sup >− 7 </ sup > moles per liter.

Since pH is defined as the negative logarithm of the concentration of hydronium ions, acids thus have pHs of less than 7.

Some parts of the British press and British government expected the campaign to be over within months, and the protracted war gradually became less popular, especially after revelations about the conditions in the concentration camps ( where 26 thousand women and children died of disease and malnutrition ).

An important factor is that the bubble contains mainly inert noble gas such as argon or xenon ( air contains about 1 % argon, and the amount dissolved in water is too great ; for sonoluminescence to occur, the concentration must be reduced to 20 – 40 % of its equilibrium value ) and varying amounts of water vapor.

The first 1 % or so of distillate that is produced, called the " head ," has an alcohol concentration of about 83 % ( 166 US proof ) and an unpleasant odour, so it is discarded ( generally, mixed with another batch of low wine, thereby entering the distillation cycle again ).
