Explain

In AQA GCSE Biology, Explain means give a linked reason, mechanism, or cause-and-effect account rather than naming a fact. For Animal tissues, organs and organ systems, use Explain to support the objective to explain the consequences of faulty heart valves. Related approved keywords for this objective include valves. This definition is deliberately scoped to Coronary heart disease: a non-communicable disease, so it preserves this concept without merging it with neighbouring key terms.
