Question
- A. GX23: Use the daphnia temperature assay. Measure heart-rate tally. Change water-bath setting; record the dependent variable from the data table; hold acclimation interval 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. Keep locus-variant evidence separate from allele-frequency model evidence and selection evidence. Evaluate validity, reliability, limitation, conclusion and improvement.
- B. GX23: Use casual observations of daphnia temperature assay; omit expected values and ignore sample size. Evaluate validity, reliability, limitation, conclusion and improvement.
- C. GX23: Change water-bath setting and acclimation interval together, then claim correlation proves causation. Evaluate validity, reliability, limitation, conclusion and improvement.
- D. GX23: Discuss Define a population as organisms of the one species in a space and time that can potentially i without a null hypothesis, controlled variable or bias check. Evaluate validity, reliability, limitation, conclusion and improvement.
Answer
The correct answer is: GX23: Use the daphnia temperature assay. Measure heart-rate tally. Change water-bath setting; record the dependent variable from the data table; hold acclimation interval 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. Keep locus-variant evidence separate from allele-frequency model evidence and selection evidence. Evaluate validity, reliability, limitation, conclusion and improvement.
Explanation
This works because the answer is anchored to Define a population as organisms of the same species in a space and time that can potentially interbreed.: it names the biological idea, applies it within Populations, and links the evidence to a consequence. GX23: The correct option is supported by heart-rate tally, water-bath setting, controlled acclimation interval, representative sampling, observed and expected values, and a cautious correlation judgement. Evaluate validity, reliability, limitation, conclusion and improvement. If data are provided, the answer should identify the pattern first and then explain the biological significance.
Common mistake
Populations common mistake 1
Giving a vague answer instead of directly addressing: Define a population as organisms of the same species in a space and time that can potentially interbreed..
Answer by clearly explaining how to define a population as organisms of the same species in a space and time that can potentially interbreed..
