Learning outcomes By the end of this unit you should be able to: Section 1 recognise the equation of a line in the plane; determine the point of intersection of two lines in the plane, if it exists; recognise the one-one correspondence between the set of points in three-dimensional space and the set of ordered triples of real numbers; recognise the equation of a plane in three dimensions.

7.4 Elixirs of the nervous system: neurotrophins According to Section 7.2 axons obtain an elixir from targets at their synapses. Confirmation that there is indeed an elixir came from a series of events that reveals how much of science really works.

1.3 Wider aspects of business and company law So far, we have touched on just a few of the many aspects of the law which relates to companies and other businesses. It will be useful at this point to consider how these areas fit into some wider issues raised by the study of law in general. For example: The law relating to businesses such as companies and partnerships regulates important areas of daily life, and allows you to see that there is a connection between the law and the way in which people
2.1.3 Concept cards Another way to tackle unfamiliar words is to start a ‘concept card’ system, using index cards. When you meet a word which seems important, take a new card and write the word at the top, followed by any useful information you have found. File the cards alphabetically and add details as you come across new information. (It is worth getting an index card box anyway, then you can try out various ways of using it to organise your studies.) 7.7 Drawing ideas together This key skill has used a three-stage framework for developing your skills. By developing a strategy, monitoring your progress and evaluating your overall approach, you take an active role in your own learning. But learning does not necessarily follow a path of steady improvement, it involves change: revisiting ideas, seeing things from different perspectives, tackling things in different ways.

We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it. Introduction This course is an introduction to chemistry concepts, using water as the main illustration. Much of the course is devoted to exploring the smallest water particle - a water molecule - what it is and how it gives rise to the particular properties of water. The course also explains powers of ten and scientific notation, which are a convenient way of expressing both very large and very small numbers. It is a good introduction to science. This OpenLearn course provides a sample of level 1 s Introduction Nature Matters considers environmental responsibility and what may matter from a caring perspective and an accountability perspective. A reading by Andrew Light reflects on four key debates in environmental ethics regarding the way in which nature is valued, and prompts the question on how such debates might inform environmental responsibility. Section 2 examines the formal processes involved in developing accountability in the context of sustainable development. The persuasiveness of t 6 Phylogeny and cladistic analysis In Section 3.3 the point was made that many physiologists consider that desert birds are successful because of their avian physiology, not because of any specific adaptations. While Williams and Tieleman's research on hoopoe larks demonstrated that desert species are capable of flexibility in metabolic rate and evaporative water loss, it suggested that adaptation is important too. The selective advantages of lowered BMR and TEWL for desert birds include reduced energy demand, and lower produc 1 Wave energy The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. Not surprisingly the ma Design Introduction ‘Environment’ is one of the more popular words in the management lexicon, most generally understood to be referring to ‘something outside’. But common usage today often interprets the Environment (with or without the capital ‘E’) as referring to the planetary ecosystem. On that basis the Environment includes such things as global warming, the state of the ozone layer, deforestation and the means of energy generation.

This free course looks at the process of design, from assessing the complexity of design as an activity to exposing the difficulty in making general conclusions about how designers work. You will be able to identify innovation in a wide variety of designed objects and evaluate the impact of this innovation.

Sweatshops and the exploitation of workers are often linked to the globalised production of ‘big brand’ labels. This unit examines how campaigners have successfully closed the distance between the brands and the sweatshops, while others argue that such production ‘kick starts’ economies into growth benefiting whole communities.
