Question
- A. RH-F6: use a clear method with muscle spindle reflex record; independent variable is tap force, dependent variable is response time, and controlled variable is participant posture; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to reflex arc coordination.
- B. Describe muscle spindle reflex record without naming the independent variable, dependent variable or controlled variable.
- C. Change tap force and participant posture together, then avoid evaluating reliability or uncertainty.
- D. State only that homeostasis occurs and ignore reflex arc coordination.
Answer
The correct answer is: RH-F6: use a clear method with muscle spindle reflex record; independent variable is tap force, dependent variable is response time, and controlled variable is participant posture; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to reflex arc coordination.
Explanation
The correct option is RH-F6: use a clear method with muscle spindle reflex record; independent variable is tap force, dependent variable is response time, and controlled variable is participant posture; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to reflex arc coordination. It supports Explain control of blood water potential using ADH because it names method, variable choices and evaluation, then connects the evidence to reflex arc coordination.
Common mistake
response and homeostasis practical reasoning mistake
Describing Explain control of blood water potential using ADH without naming variables, controls or evaluation of the evidence.
For practical reasoning, state the method, independent variable, dependent variable and one controlled variable; keep the control constant; then evaluate validity, reliability, accuracy, precision, uncertainty, risk and possible improvements. Then link the practical evidence to Explain control of blood water potential using ADH.
