This is a 2 year A Level course, which consists of 8 topics. 1) Biological molecules – All life on earth shares a common chemistry. Carbohydrates, lipids, proteins, nucleic acids and water interact to ensure the correct functioning of all living organisms. 2) Cells – All life on Earth exists as cells. These have basic features in common. Differences between cells are due to the addition of extra features. Cells must be able to divide and communicate with each other. 3) Organisms exchange substances with their environment – The internal environment of a cell or organisms if different from its external environment. Substances must be exchanged across specialised surfaces to cope with any changes. 4) Genetic information, variation and relationships between organisms – Genetic diversity within and between species is caused by variation within the DNA. Mutations in the DNA lead to variations in organisms structure and function. 5) Energy transfers between organisms – Life depends on continuous transfers of energy. Respiration and photosynthesis are the two most important reactions which allow this transfer. 6) Organisms respond to changes in their internal and external environment – There are changes in the internal and external environment in all organisms. Once a change or stimulus occurs, organisms must initiate and control their response. 7) Genetics, populations, evolution and ecosystems – The theory of evolution underpins modern Biology. All new species arise from existing species living in changing environmental conditions. 8) The control of gene expression – Cells are able to control their metabolic activities by regulating the transcription and translation of their genome. This allows them to become more specialised, forming tissues and organs. There are 12 set practical activities and the written papers will assess knowledge and understanding of these.
