2.5.1 Summary of Section 2

Desert animals are classified in terms of their body size and physiology into three groups: evaders, evaporators and endurers. The logic for this classification is that the smaller the animal, the larger its surface area to volume ratio. Small animals therefore gain and lose heat faster than large animals, warming rapidly when exposed to intense solar radiation, and cooling rapidly at night. Small endothermic evaders, e.g. kangaroo rats, rest in cool microenvironments, e.g. shade or burrows,

1.3 Attending to sounds

From the earlier sections, you will appreciate that the auditory system is able to separate different, superimposed sounds on the basis of their different source directions. This makes it possible to attend to any one sound without confusion, and we have the sensation of moving our ‘listening attention’ to focus on the desired sound. For example, as I write this I can listen to the quiet hum of the computer in front of me, or swing my attention to the bird song outside the window to my ri

3.1 Introduction

The simplest and oldest way of storing surface water is in reservoirs and this has been done for thousands of years. Most reservoirs are still built to increase water supplies, but some are also built for other purposes, especially for generating hydroelectric power and for protection against floods. The Tennessee River in the United States, for example, has reservoirs to trap and store water that would otherwise cause floods, the water being released when the height of the river falls to saf

2.12 Fluid balance

Although a person can survive for several weeks without food, without fluids, someone can survive for only a few days. A loss of water equivalent to just 1% of body weight is enough to make someone feel thirsty and to have an effect on ability to concentrate. Such a loss has been shown in some studies in schools to result in a 10% decrease in the mental performance of children. A 4% loss results in dizziness and reduced muscle power. By the time there is a 6% loss, the heart is racing and swe

6 Conclusion

William Wilberforce died on 29 July 1833, two days after hearing that the legislation for the abolition of slavery in British dominions had successfully completed its passage through the House of Commons, a fitting conclusion to the work he had begun nearly half a century before.

The Practical View both reflected and contributed to a major shift in religious consciousness of which the continuing growth of the Evangelical movement was the most striking manifestation. Methodist num
