September 2018 - GCSE Science 5-a-day
Every GCSE Science sheet published in September 2018, with answers. Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
Every sheet in September 2018
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st September 2018Name the gland that monitors and controls blood glucose concentration.
- 2nd September 2018Explain why genetic engineering can introduce a new characteristic in a single generation, while selective breeding cannot.
