Cells divide by two different processes: mitosis and meiosis.
(a) Compare mitosis and meiosis by stating:
i. The number of daughter cells produced by each process.
ii. Whether the daughter cells are genetically identical or different.

Stem cells have the potential to revolutionise medicine.
(a) Describe the difference between embryonic stem cells and adult stem cells found in bone marrow in terms of their ability to differentiate.
(b) Explain the process of 'therapeutic cloning' and discuss why this technique is used to prevent the rejection of transplanted tissues.
(c) Give one social or ethical argument against the use of embryonic stem cells in medical research.
