  • Q #2: A study found two processes. Process A and Process B, are to be correlated. Which of the following is true for these processes?

    A. The study indicates that Process A causes Process B

    B. The study cannot indicate whether Process A and B have a negative relationship

    C. The study does not indicate a causal relationship between the processes.

    D. The study cannot indicate whether Process A and B have a positive relationship

    Answer Explanation

    Correlation does not imply causation. Even if two processes are found to be correlated, it does not necessarily mean that one causes the other. It could be that they are both influenced by a third factor, or the correlation could be coincidental. Therefore, the study does not indicate a causal relationship between the processes.

    B. Lysosomes

    C. Centrosomes

    D. Ribosomes
