6.1 Direct proportion

The first type of proportion relationship is known as direct proportion. Two quantities are said to be directly proportional to each other if when one doubles, triples, quadruples, the other also doubles, triples, quadruples. For example, if you buy three times as many items as usual, you would expect to have to pay three times as much money (unless there was some special offer available), because the price is directly proportional to the number of items bought.

9.4 Summary of Section 9

This section has illustrated what has to be done, by way of a long-term study, to yield meaningful information on the relationship between genes and development and the behaviour of the organism. It also illustrates the hugely complex nature of the relationship between genes and development and the behaviour of the organism. Yet this complexity is not the exception, it is the rule.

5.5.1 Monitors

Nearly all computers are supplied complete with a monitor which opens a window onto the machine's digital world. Without one we could have little idea about what the computer was doing, or even whether it was working at all.

There are two main types of monitor: the CRT (cathode ray tube) and LCD (liquid crystal display). A CRT monitor looks like a television screen, and works in a similar way to a TV or a scanner. A beam of electrons is fired from a gun at the back of the

Visions of protest: Graffiti
This free course, Visions of protest: Graffiti, introduces students to contrasting understandings of graffiti. It draws on a wide range of graffiti examples, including mystery zebras in Hackney, fish graffiti in Morecambe, 'tags' in a Milton Keynes underpass, a McDonald's advert and exhibits at a highly established art gallery, the Tate Modern.

1.1.1 Chromosomes and the life cycle

The type of nuclear division called meiosis is intimately linked to the life cycle of organisms that reproduce sexually.

Chromosomes are present in the cells of all eukaryotes. Their number varies enormously and is characteristic for each species. The parasitic worm Ascaris lumbricoides has only four chromosomes whereas some ferns, such as the adder's tongue fern (Ophioglossum vulgatum), have more than 1 000 chromosomes. Most eukaryotes have between 10 and 50 chromosomes;

4.3 Regulation

Increasing demand for wireless technology means that the radio frequencies must be carefully managed and allocated by governments to satisfy all the different users and to prevent interference between them. (You may remember the UK Government's auction of 3G radio licences in Spring 2000 which raised approximately £22.5 billion.)

Before transmitting radio signals, organisations must usually obtain a licence permitting them to use a specified frequency or band of frequencies. However, o

2.1 How the programme progresses

The programme takes the form of a visit to Glasgow. We talked to people and asked about their image(s) of Glasgow and whether these had changed – what was the ‘old’ image; what is the ‘new’; how has it changed; what will it be like in another ten years?

The five main participants have different experiences of Glasgow and these are represented in the images which they hold and aspects of the city's character which they highlight. The themes and ideas behind the programme are al
