3.1 Introduction
Animal life has adapted to survive in the most unlikely and inhospitable habitats. This unit looks at the surprisingly diverse desert climates throughout the world and mammals, birds, lizards and amphibians that survive there. It splits these animals into three groups according to their strategy for survival: evaders, evaporators and endurers, then discusses how these strategies work on a biochemical and physiological level.
Introduction
Managing eutrophication is a key element in maintaining the earth's biodiversity. Eutrophication is a process mostly associated with human activity whereby ecosystems accumulate minerals. This unit explains how this process occurs, what its effects on different types of habitat are, and how it might be managed.

Introduction
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This unt takes a look at the 'science behind the headlines' and the complex interactions between scientific and social factors. By the end of the unit it's hoped that you will have a clearer idea of both what is GM makes possible as well as what may be thought desirable.

1 Genetic manipulation of plants and GM crops: an introduction
Genetic manipulation of crops is an issue of great current interest and controversy. This unit covers some of the basic science that underpins the debate and examines the hotly contested case study of the development of ‘Golden Rice’. By looking at the science 'behind the headlines' you will acquire a clearer idea of both what is possible in GM science and what may be desirable.

Introduction
Climate change is a key issue on today’s social and political agenda. This unit explores the basic science that underpins climate change and global warming.

Introduction This unit includes reading and writing activities that are geared to developing the use of memory, observation and the senses. The aim is to develop your perceptual abilities, honing your capacity to see detail in the world. You will be encouraged to start seeing the familiar in a new way and to make good use of your own personal history. This unit is an adapted extract from the Open University courseAuthor(s):
Introduction
Stars can necessarily be observed only at a distance. This unit introduces the Hertzsprung–Russell diagram, an essential tool in understanding the nature of stars. You should have some understanding of the basic stellar properties of luminosity and temperature in order to get the most from the unit.

Introduction
This unit is concerned with the technique of expressing a periodic function as a sum of terms, where each term is a constant, a sine function or a cosine function. There is a strong analogy with the technique of expressing a (non-periodic) function as a Taylor series, which is a sum of terms that are powers of the independent variable(s); in both cases, working with just the first few terms generally gives a useful approximation. This unit assumes the following background knowledge: the definit
Introduction The topic of ‘governance’ is one that has gained popularity, and the term is now used to embrace a range of concepts. This unit establishes some basic principles that will form the basis of your study. You will have the opportunity to consider how well these principles match up with your own observations of corporate organisations and behaviour This material is from our archive and is an adapted extract from Issues in international financial reporting (B853) which is no
Introduction
This unit introduces you to analysing academic writing and, in particular, the way an article might be structured to clearly explain an investigation to other researchers. It explores observation of children and young people using qualitative observation approaches in small-scale studies.
Introduction We begin this unit by looking at an estuary, a place where sea, land and sky meet. We have chosen a particular estuary: the Blackwater estuary on the Essex coast in eastern England. Although the Blackwater has its own unique characteristics, it is used here as a setting, a device for approaching the study of environments. Like any other estuary, the Blackwater brings together a diverse range of processes, elements and issues that constitute the environment. It offers us a way into thinking ab
Introduction to improving own learning and performance
This unit focuses on higher level skills. Skills development is complementary to other learning – it cannot be done in isolation. The higher level skills in this material aim to raise your awareness of the processes of learning and development – other subject-based material must supply the context and motivation for this. Key skills underpin the ability to carry out successfully, and improve on, a wide range of tasks in higher education, employment and wherever there is a continuation of le
