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 that coronary heart disease happens when fatty material builds up in the coronary arteries. Related approved keywords for this objective include coronary heart disease. 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.
