The blood, however, has a number of defensive functions which limit the effects of many pathogens. A knowledge of the way in which genes code information, that results in the synthesis of specific proteins can lead to an understanding of the way in which certain diseases are caused, as well as allowing the production of specific proteins that can be used in their treatment and control. Non-communicable diseases such as heart disease and cancers also have a significant impact on human health. Biotechnology has allowed the development of a variety of methods for the diagnosis and control of disease. Teacher assessment of practical skills.
Genetic information is copied and transmitted from generation to generation.
Natural selection acting on genetic variation is thought to have led to the enormous diversity of living organisms. B. The Biology of Ecosystems Living organisms do not live in isolation but form structured communities within dynamic and well-defined ecosystems through which energy flows and in which nutrients are cycled. This module also allows consideration of some of the ways in which human activity can impose far-reaching effects on the environment. It is expected that candidates will carry out fieldwork involving the collection of quantitative data from at least one habitat and the application of elementary statistical analysis to the results. Living organisms do not live in isolation.
