...footprints from the crime scene showed that the culprit’s trainers had damage that did not match the trainers later recovered from the accused. However, the expert assigned this evidence a ‘likelihood ratio’ of 1 (meaning that the evidence was neither exculpatory nor inculpatory). Logically, the value should have been less than 1 (because it was exculpatory). The...

...carbon dioxide (taken in from the air through pores, called stomata, in their leaves) to make sugars. Plants can use these sugars, together with minerals which are dissolved in the water in the soil, as the raw materials for all the other types of molecule that the plant needs for its healthy growth. A crucial role in photosynthesis is played by the green pigment,...

...carbon dioxide by the gut bacteria. The carbon dioxide is excreted with the respiratory gases, but the fate of the highly soluble, and in high concentrations toxic, ammonium ions (NH4 +) is more interesting. In dormant bears, the blood concentrations of amino acids, total protein, urea and uric acid during dormancy are similar to those of active bears that are feeding...
