Step-by-step AQA A Level Biology lessons by topic, building up to exam-style questions. Build a strong foundation in cell biology and biochemistry early on, since later topics on genetics, ecology and physiology all draw on these core concepts.
Biological molecules
Proteins
Nucleic acids are important information-carrying molecules
Cells
Organisms exchange substances with their environment
Genetic information, variation and relationships between organisms
Energy transfers in and between organisms (A-level only)
Organisms respond to changes in their internal and external environments (A-level only)
Stimuli, both internal and external, are detected and lead to a response (A-level only)
Nervous coordination (A-level only)
Homeostasis is the maintenance of a stable internal environment (A-level only)
Genetics, populations, evolution and ecosystems (A-level only)
The control of gene expression (A-level only)
Gene expression is controlled by a number of features (A-level only)
Gene technologies allow the study and alteration of gene function allowing a better understanding of organism function and the design of new industrial and medical processes (A-level only)
