All 19 topics of Cambridge AS & A Level Biology 9700: AS topics 1 to 11, then A Level topics 12 to 19. Every topic has lessons with interactive labs, a question bank and revision notes, and practical trainers for Paper 3 and Paper 5 are ready too.
Trainers for the practical papers, marked the way examiners mark. See every practical trainer.
Light and electron microscopes, calibrating the eyepiece graticule, and the ultrastructure of eukaryotic and prokaryotic cells.
Tests for biological molecules, carbohydrates and lipids, proteins, and the properties of water.
How enzymes lower activation energy, and the factors that affect their rate, including inhibitors and Vmax and Km.
The fluid mosaic model and movement across membranes: diffusion, osmosis, active transport and bulk transport.
Replication and division of nuclei and cells, and how chromosomes behave during mitosis.
The structure of DNA and RNA, semi-conservative replication, and transcription and translation.
The structure of xylem and phloem, transpiration and translocation.
The circulatory system, the transport of oxygen and carbon dioxide, and the heart.
The structure and function of the human gas exchange system.
Cholera, malaria, tuberculosis, HIV/AIDS and measles, and how antibiotics work.
Phagocytes and lymphocytes, antibodies, vaccination and immunity.
ATP, the stages of aerobic respiration, anaerobic respiration and respiratory quotients.
Photosynthesis as an energy transfer process, and investigating limiting factors.
Negative feedback, temperature, blood glucose and water in mammals, and stomata in plants.
Nerves, synapses, muscle contraction and hormones in mammals, and control in plants.
Meiosis, genetic crosses and the chi-squared test, the roles of genes in the phenotype, and gene control.
Variation, natural and artificial selection, and evolution and speciation.
Domains and kingdoms, measuring biodiversity in the field, and conservation.
Recombinant DNA, PCR and electrophoresis, genetic technology in medicine and GM organisms in agriculture.
IGCSE Biology 0610 covers the ideas every AS topic builds on, with the same practical skills at a simpler level.
