Question
- A. RH-H8: use a clear method with plant shoot curvature assay; independent variable is direction of light, dependent variable is angle of curvature, and controlled variable is shoot length; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to auxin redistribution.
- B. Describe plant shoot curvature assay without naming the independent variable, dependent variable or controlled variable.
- C. Change direction of light and shoot length together, then avoid evaluating reliability or uncertainty.
- D. State only that homeostasis occurs and ignore auxin redistribution.
Answer
The correct answer is: RH-H8: use a clear method with plant shoot curvature assay; independent variable is direction of light, dependent variable is angle of curvature, and controlled variable is shoot length; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to auxin redistribution.
Explanation
The correct option is RH-H8: use a clear method with plant shoot curvature assay; independent variable is direction of light, dependent variable is angle of curvature, and controlled variable is shoot length; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to auxin redistribution. It supports Explain resting potential, action potential and nerve impulse transmission because it names method, variable choices and evaluation, then connects the evidence to auxin redistribution.
