Original practice
A graph shows enzyme activity rising with temperature until it falls sharply. What biological explanation should be tested?
Activity rises as particles gain kinetic energy, then falls when enzyme structure changes enough to reduce active-site function.
Why include a control group when testing fertilizer effect on plant growth?
The control gives a baseline so growth differences can be linked more confidently to the fertilizer treatment.
A diagram shows DNA transcribed to RNA. What weak spot should be logged if a student calls the RNA product a protein?
Log it as gene expression sequence confusion: transcription makes RNA; translation uses RNA to build protein.
