Animals at the extremes: polar biology

...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...

...carbon emissions. a. Around 42% b. Around 62% c. Around 82% The correct answer is c. c. Yes, but 65% of people were wrong. Fossil fuels are still the dominant source of energy; despite advances in the availability and use of renewable energy, fossil fuels constitute around 82% of global energy use (e.g. BP, 2020). There’s still a long way to go to cut harmful carbon...

...carbon-based polymers containing low atomic-number atoms – mainly carbon, nitrogen, oxygen and hydrogen. Bone absorbs X-rays more strongly than the surrounding soft tissue (Figure 1). Why is this? Figure 1 X-ray of a broken bone. Bone not only contains elements with higher atomic number than the surrounding soft tissue, such as calcium and phosphorus, but also is denser...

...carbon dioxide (CO2) as the waste products of combustion. Although definitions of the Anthropocene have largely focused on how humans have controlled fire for industrial purposes, this period has also been marked by an increase in wildfires and their intensity. For millions of years many plants and animals have taken advantage of naturally occurring wildfires, triggered...
