Question

A. CGEQ21: Use stem-cell differentiation dish. Independent variable: growth-factor mix. Dependent variable: marker-positive cells. Controlled variable: passage number. Method: identify the independent variable, dependent variable and controlled variable; keep controls constant; evaluate validity, reliability, accuracy, precision, uncertainty, risk, limitation, conclusion and improvement. Link the result to Explain RNA interference as inhibition of translation.; transcription makes RNA and translation makes polypeptide.
B. CGEQ21: Change growth-factor mix and passage number together, then ignore uncertainty and controls.
C. CGEQ21: Record marker-positive cells without a method, dependent variable or evaluation.
D. CGEQ21: Describe gene expression generally but omit the controlled variable and conclusion.

Answer

The correct answer is: CGEQ21: Use stem-cell differentiation dish. Independent variable: growth-factor mix. Dependent variable: marker-positive cells. Controlled variable: passage number. Method: identify the independent variable, dependent variable and controlled variable; keep controls constant; evaluate validity, reliability, accuracy, precision, uncertainty, risk, limitation, conclusion and improvement. Link the result to Explain RNA interference as inhibition of translation.; transcription makes RNA and translation makes polypeptide.

Explanation

A precise explanation should use the context, quote or interpret any evidence, and return to Explain RNA interference as inhibition of translation. rather than giving a generic biology statement. CGEQ21: The option is correct because it states method, independent variable, dependent variable, controlled variable, controls, evaluation and a valid conclusion for stem-cell differentiation dish. If data are provided, the answer should identify the pattern first and then explain the biological significance.
