Question
- A. RH-C3: use a clear method with synapse drug trial; independent variable is drug concentration, dependent variable is postsynaptic response, and controlled variable is synapse preparation age; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to neurotransmitter diffusion and receptor binding.
- B. Describe synapse drug trial without naming the independent variable, dependent variable or controlled variable.
- C. Change drug concentration and synapse preparation age together, then avoid evaluating reliability or uncertainty.
- D. State only that homeostasis occurs and ignore neurotransmitter diffusion and receptor binding.
Answer
The correct answer is: RH-C3: use a clear method with synapse drug trial; independent variable is drug concentration, dependent variable is postsynaptic response, and controlled variable is synapse preparation age; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to neurotransmitter diffusion and receptor binding.
Explanation
The correct option is RH-C3: use a clear method with synapse drug trial; independent variable is drug concentration, dependent variable is postsynaptic response, and controlled variable is synapse preparation age; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to neurotransmitter diffusion and receptor binding. It supports Explain control of blood water potential using ADH because it names method, variable choices and evaluation, then connects the evidence to neurotransmitter diffusion and receptor binding.
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.
