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 how defects in the immune system can increase the chance of infectious disease. Related approved keywords for this objective include disease. This definition is deliberately scoped to Health issues, so it preserves this concept without merging it with neighbouring key terms.
