CAIE A Level Biology 9700 · Classification, biodiversity and conservation
The Sumatran forest deer (Elaphodus sumatranus) is critically endangered, with fewer than 100 individuals remaining in the wild. Conservationists are considering assisted reproduction techniques to boost the population. Outline how in vitro fertilisation (IVF), embryo transfer and surrogacy could be used to help conserve this species.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
