Every sheet in November 1975
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st November 1975A plant grown in the shade is shorter than a genetically identical plant of the same species grown in full sunlight. State whether this difference is genetic variation, environmental variation, or both.
- 2nd November 1975State one method used to try to maintain biodiversity.
