Explain

In AQA GCSE Biology, Explain means give a linked reason, mechanism, or cause-and-effect account rather than naming a fact. For Principles of organisation, use Explain to support the objective to explain that an organ is made from different tissues working together to perform a function. Related approved keywords for this objective include tissues. This definition is deliberately scoped to Principles of organisation, so it preserves this concept without merging it with neighbouring key terms.
