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 cancer results from changes in cells that cause uncontrolled growth and division. Related approved keywords for this objective include cancer. This definition is deliberately scoped to Cancer, so it preserves this concept without merging it with neighbouring key terms.
