...account, but you might be able to explain the relative sizes of the statistics. Answer You may have got something similar to Figure 34, with the decision level fairly close to 1. [Described image] Figure 34 Asymmetrical decision level Because the decision level is so close to 1, noise-affected 0 signals very rarely go beyond the decision level. This is why false...

...account. The emphasis is not on the tools (systems tools or other tools) being ‘used’, but rather the ‘user’ of the tools. An animated tutorial in two parts describing the workings of the STiP heuristic is available on OpenLearn. Activity 2 The systems thinking practitioner Read the final chapter Systems Approaches Epilogue. You will be invited to revisit this...

...account for all the substances that exist and that can be made, but in fact there are just 118 different types of atom that have been observed. These are known as the chemical elements and of those 118, only about 90 occur naturally. Each element is represented by a chemical symbol, consisting of one or two letters, for example, H is for hydrogen and He is helium. An...

...account for planets orbiting stars other than the Sun. These planets are called exoplanets. The first planet orbiting another Sun-like star was discovered in 1995, and since then astronomers have found over 4000 of these exoplanets. A star along with its exoplanets is known as a planetary system. We now know that our own Solar System is not unique: it is one planetary...

...account when interpreting samples. Orientation Most histological sections are 2D slices, from a 3D piece of tissue. Exactly what will be seen on the microscope slide depends on the plane of the section; that is, the position of the microtome cut, in relation to the anatomical structures in the tissue. Clinicians attempt to cut tissues in a plane that allows the underlying...

...account for the differences in hardness between the two minerals? Diamond has a three-dimensional bonding pattern, with identical bonding in all directions, and no 'weak' directions. Graphite has a mainly two-dimensional pattern, with sheets of C-C bonds. Bonds between the sheets are very weak, so sheets can easily slide past each other, explaining graphite's use as a...

...account, explain how natural selection could have caused an increase in beak size in this population of ground finches. The adult survivors of the drought were the ones with the largest beaks because they could still crack large seeds. These birds then mated and because beak size is heritable and is passed on to offspring, the chicks from these birds inherited large beak...
