Question
- A. GX24: Use the seed bank germination tray. Measure emergence totals. Change soil-depth layer; record the dependent variable from the data table; hold sterile tray control constant. Use random/systematic sampling, representative sample size and bias check. Compare observed and expected values; use critical value, significance and null hypothesis. Correlation means association; correlation does not prove causation. Gene: DNA locus. Allele: variant form. Hardy-Weinberg: allele-frequency model. Natural selection: differential reproductive success.
- B. GX24: Use casual observations of seed bank germination tray; omit expected values and ignore sample size.
- C. GX24: Change soil-depth layer and sterile tray control together, then claim correlation proves causation.
- D. GX24: Discuss Evaluate conservation methods and ecosystem management. without a null hypothesis, controlled variable or bias check.
Answer
The correct answer is: GX24: Use the seed bank germination tray. Measure emergence totals. Change soil-depth layer; record the dependent variable from the data table; hold sterile tray control constant. Use random/systematic sampling, representative sample size and bias check. Compare observed and expected values; use critical value, significance and null hypothesis. Correlation means association; correlation does not prove causation. Gene: DNA locus. Allele: variant form. Hardy-Weinberg: allele-frequency model. Natural selection: differential reproductive success.
Explanation
This works because the answer is anchored to Evaluate conservation methods and ecosystem management.: it names the biological idea, applies it within Populations in ecosystems, and links the evidence to a consequence. GX24: The correct option is supported by emergence totals, soil-depth layer, controlled sterile tray control, representative sampling, observed and expected values, and a cautious correlation judgement. If data are provided, the answer should identify the pattern first and then explain the biological significance.
