What you will learn
In this course students will learn exactly what they need to know for their biology exams. Students will learn about:
UNIT 1: ECOLOGY AND THE ENVIRONMENT
Understand the terms population, community, habitat and ecosystem
Understand the term biodiversity
Understand how abiotic and biotic factors affect the population size and distribution of organisms
Understand the names given to different trophic levels, including producers, primary, secondary and tertiary consumers and decomposers
Understand the concepts of food chains, food webs, pyramids of number, pyramids of biomass and pyramids of energy transfer
Understand the transfer of substances and energy along a food chain
Understand why only about 10% of energy is transferred from one trophic level to the next
Describe the stages in the carbon cycle, including respiration, photosynthesis, decomposition and combustion
Describe the stages in the nitrogen cycle, including the roles of nitrogen fixing bacteria, decomposers, nitrifying bacteria and denitrifying bacteria (specific
Understand the biological consequences of pollution of air by sulfur dioxide and carbon monoxide
Understand that water vapour, carbon dioxide, nitrous oxide, methane and CFCs are greenhouse gases
Understand how human activities contribute to greenhouse gases
Understand how an increase in greenhouse gases results in an enhanced greenhouse effect and that this may lead to global warming and its consequences
Understand the biological consequences of pollution of water by sewage
Understand the biological consequences of eutrophication caused by leached minerals from fertiliser
Understand the effects of deforestation, including leaching, soil erosion, disturbance of evapotranspiration and the carbon cycle, and the balance of atmospheri
UNIT 2: USE OF BIOLOGICAL RESOURCES
Describe how glasshouses and polythene tunnels can be used to increase the yield of certain crops
Understand the effects on crop yield of increased carbon dioxide and increased temperature in glasshouses
Understand how the use of fertiliser can increase crop yield
Understand the reasons for pest control and the advantages and disadvantages of using pesticides and biological control with crop plants
Understand the role of yeast in the production of food including bread
Understand the role of bacteria (Lactobacillus) in the production of yoghurt
Understand the use of an industrial fermenter and explain the need to provide suitable conditions in the fermenter, including aseptic precautions, nutrients, op
Understand the methods used to farm large numbers of fish to provide a source of protein, including maintaining water quality, controlling intraspecific and int
Understand how selective breeding can develop plants with desired characteristics
Understand how selective breeding can develop animals with desired characteristics
Understand how restriction enzymes are used to cut DNA at specific sites and ligase enzymes are used to join pieces of DNA together
Understand how plasmids and viruses can act as vectors, which take up pieces of DNA, and then insert this recombinant DNA into other cells
Understand how large amounts of human insulin can be manufactured from genetically modified bacteria that are grown in a fermenter
Understand how genetically modified plants can be used to improve food production
Understand that the term transgenic means the transfer of genetic material from one species to a different species
Describe the process of micropropagation (tissue culture) in which explants are grown in vitro
Understand how micropropagation can be used to produce commercial quantities of genetically identical plants with desirable characteristics
Describe the stages in the production of cloned mammals involving the introduction of a diploid nucleus from a mature cell into an enucleated egg cell, illustra
Understand how cloned transgenic animals can be used to produce human proteins
