Paraphrase citation

Use the citation to the endpoint in each response

stick to OpenStax and Lumen Learning, or A-Level Biology textbooks

Try to give additional specific facts and details like numerical information, specific cellular/histological details.

Reduced the surrounding wording or opening sentences to instead directly describe or explain versus the question/AC instructions

Extra factual additions to cover a wider array of detail relative to the criteria.
