3.5.1 Final arousal

Emergence can be viewed as the final step in the series of periodic arousals. Instead of re-entering hibernation, the animal maintains the euthermic condition. The cue for maintaining this final arousal is probably not temperature, as some species emerge when T a is well below zero. It is also difficult to see how arousal could be affected by daylength, since the hibernating animal is usually underground in a cavity or a burrow. Perhaps fat or food stores reach a minimum lev

Introduction

James Clerk Maxwell produced a unified theory of the electromagnetic field and used it to show that light is a type of electromagnetic wave. This prediction dates from the early 1860s when Maxwell was at King's College, London. Shortly afterwards Maxwell decided to retire to his family estate in Galloway in order to concentrate on research, unhindered by other duties. He was lured out of retirement in 1871, when he became the first professor of experimental physics in the Cavendish Laboratory

2.9 Iron (Fe)

The ability of blood to carry oxygen is due to the presence of the red pigment, haemoglobin, present in red blood cells. Haemoglobin is a protein formed from four polypeptide chains called globins, in the centre of each of which is a small non-protein part called a haem group (haima is Greek for ‘blood’). Each of the haem groups has an iron atom within it (Author(s): The Open University

3.1 Background

In practice, there is almost always some element of risk (in the technical sense of ‘uncertainty’) in any investment return. There is in finance the theoretical concept of a truly risk-free asset, but at the moment it is sufficient just to be aware of the main factors causing risk or uncertainty in practice. These are:

  • maturity

  • liquidity

  • variability of income

  • default or credit risk
