Question
- A. RH-A1: use a clear method with blood glucose graph after insulin injection; independent variable is dose of insulin, dependent variable is blood glucose concentration, and controlled variable is time after injection; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to negative feedback by pancreatic hormones.
- B. Describe blood glucose graph after insulin injection without naming the independent variable, dependent variable or controlled variable.
- C. Change dose of insulin and time after injection together, then avoid evaluating reliability or uncertainty.
- D. State only that homeostasis occurs and ignore negative feedback by pancreatic hormones.
Answer
The correct answer is: RH-A1: use a clear method with blood glucose graph after insulin injection; independent variable is dose of insulin, dependent variable is blood glucose concentration, and controlled variable is time after injection; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to negative feedback by pancreatic hormones.
Explanation
The correct option is RH-A1: use a clear method with blood glucose graph after insulin injection; independent variable is dose of insulin, dependent variable is blood glucose concentration, and controlled variable is time after injection; evaluate reliability, uncertainty, validity, sample size and bias while linking evidence to negative feedback by pancreatic hormones. It supports Describe Pacinian corpuscle and retinal photoreceptor function because it names method, variable choices and evaluation, then connects the evidence to negative feedback by pancreatic hormones.
