Students apply understanding of plant tissues and stem cells, trace drug origins from deadly nightshade, and perform calculations involving chemical quantities and unit conversion. The paper also evaluates scientific reasoning about clinical trials and biased reports. Additional questions cover the circulatory system, including heart structure, pacemaker location, and comparing arteries versus veins using figure information, plus interpreting a blood-flow trend from a blockage table.","| Please write clearly in block capitals. |  |  |  |\n| --- | --- | --- | --- |\n| Centre number |  | Candidate number |  |\n| Surname  \u003Cbr>Forename(s)  \u003Cbr>Candidate signature  \u003Cbr>I declare this is my own work. |  |  |  |\n\nGCSE  \nBIOLOGY  \nHigher Tier Paper 1 H  \nH  \nTuesday 16 May 2023 Morning Time allowed: 1 hour 45 minutes  \nMaterials  \nFor this paper you must have:  \n• a ruler  \n• a scientific calculator.  \nInstructions  \n• Use black ink or black ball-point pen.  \n• Pencil should only be used for drawing.  \n• Fill in the boxes at the top of this page.  \n• Answer all questions in the spaces provided.  \n• If you need extra space for your answer(s), use the lined pages at the end of this book.
