Animals at the extremes: polar biology

...physical process, for which the Q10 is about 1.2–1.4 in the range 0–10° C, but, like other active, enzymatic mechanisms, the Q10 of ATP-producing pathways is 2–3. So as the temperature falls, extrusion cannot keep up with inflow, ions accumulate in the cells, and the membrane potential falls, with disastrous effects in neurons, muscle, kidney and many other kinds...

...physical properties of matter. Such ‘external models’ underpinned by shared assumptions are commonplace, often to the point where we take them for granted. This can be particularly so where we try to use diagrams to represent and communicate complex information simply and quickly. Activity 1 Try to think of three examples of diagrams you see regularly in your home....
