Final answer:
The statement is false; different tests require specific handling and preservation depending on the nature of the sample. Larger sample sizes are better in scientific experiments, and experiments can be performed on humans following ethical guidelines. Moist-heat sterilization is more efficient and thus requires higher temperatures and longer periods than dry-heat sterilization.
Step-by-step explanation:
The statement that all tests require the same handling/preservation is false. Different experiments and tests involve various biological materials and substances that often call for specific storage conditions to maintain their integrity. For instance, DNA samples may require refrigeration or freezing to prevent degradation, while certain chemicals might need to be stored at room temperature away from light to remain stable.
Addressing the provided information, it is true that larger sample sizes generally provide more reliable data in scientific experiments as they can better account for variability within the population and reduce the impact of outliers. However, experiments can indeed be done on humans, but they must follow strict ethical guidelines and obtain informed consent from participants. The process of moist-heat sterilization usually requires higher temperatures and longer exposure times compared to dry-heat sterilization because the presence of water facilitates more efficient heat transfer and microbe inactivation.
