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 bile neutralises stomach acid and emulsifies fats to increase the rate of fat digestion. Related approved keywords for this objective include bile. This definition is deliberately scoped to The human digestive system, so it preserves this concept without merging it with neighbouring key terms.
