Unit 2: Science and Society
(b) Man and the Environment
7. understand that when the Earth's human population was much smaller, the effects of human activity on the environment were usually small and local.
As the population has increased, the effects on the environment have also increased. Compare the advantages and disadvantages of organic and intensive farming.

Unit 2: Science and Society
(a) The Human Body and Health
Human health is affected by a variety of factors, including infection. Scientific knowledge and technology may provide the answer to some health problems, however, advances in knowledge and technology may also raise ethical issues for both the medical profession and for society.
You need to:
26. discuss the ethical issues surrounding and how the decisions are made about the use of animals for testing drugs.

Unit 2: Science and Society
What you will need to learn
(a) The Human Body and Health
You need to:
11. understand that the nucleus in nearly all cells contains DNA. Analysis by 'genetic fingerprinting' can be used to show the similarity between two DNA samples, for instance in criminal and paternity cases.

What you will need to learn
(a) The Human Body and Health
You need to:
12. assess the issues surrounding 'gene ownership' as a result of DNA analysis and consider whether the ethical issues involved are a matter for society and beyond the scope of science to solve.

Unit 2: Science and Society
What you will need to learn
(a) The Human Body and Health
The appearance and way in which the body works are determined by genes. An understanding of DNA and the mechanism of inheritance is important for understanding the origins of some disorders and in other situations such as paternity cases.
You need to:
19. know that new genes result from changes, mutations, in existing genes and that mutations occur randomly. Mutations may be beneficial or harmful and may be passed on from parents to offspring.
20. know that cystic fibrosis is an inherited disease which causes the production of thick mucus which blocks the bronchioles. Gene therapy has been tried but there are difficulties in targeting appropriate cells and there may be side effects.

What you will need to learn:
(b) Man and the Environment
12. understand that genetic engineering involves the artificial transfer of genes into the cells of one organism from another at an early stage in their development so that they develop with desired characteristics.
13. understand that the introduction of genes from resistant plants into Soya bean plants, so increasing their resistance to herbicides, may increase the crop yield. Critically assess the issues surrounding this GM crop technology, including the need to plan scientifically valid, suitable trials to assess the possible effects in order to inform the debate for the scientific community; government policy departments; wider public opinion.
