Final answer:
Option A ('Procedures must be specific in all conditions so they are repeatable') is true, as specificity ensures consistency and repeatability. Writing procedures in paragraph form (Option B) is not always best; lists are clearer. Writing down a procedure as you go (Option C) can lack the necessary detail for others to repeat the process.
Step-by-step explanation:
In response to the question about procedures, there are several key points to consider. A) Procedures must be specific in all conditions so they are repeatable is a true statement. Having specific procedures ensures that the results are consistent and that others can replicate the process to verify the findings or apply the procedures in new contexts.
B) Writing procedures in paragraph form is not always the best approach. While paragraphs can be used to describe complex steps in detail, procedures are often more effectively communicated using numbered or bulleted lists for clarity and ease of reading. Moreover, using lists helps ensure that each step is distinct and clearly understood.
C) Writing down the procedure as you go can be acceptable in some contexts, such as documenting a novel procedure or when conducting preliminary experiments. However, for clear communication and repeatability, it is generally better to plan and write down procedures beforehand. This practice minimizes the risk of missing steps or details that may be critical for the procedure's success.
Therefore, option A is the most accurate statement in describing best practices for writing procedures.
