Evidence in the form of dried biological material is packaged in which of the following?

The correct answer is that dried biological material should be packaged in a paper bag. The reason for this choice lies in the properties of paper bags, which allow for proper ventilation. When biological materials are stored, moisture can be a concern, as it can promote the growth of mold or other contaminants. Paper bags are breathable and help to reduce the risk of moisture accumulation, which is vital for preserving the integrity of the evidence.

In contrast, other packaging options, such as plastic bags, can trap moisture, creating an environment that is not ideal for biological samples. Metal boxes may offer durability but do not provide the necessary ventilation and can lead to similar issues with moisture. A druggist fold is typically used for small isolated evidence and is not suitable for larger specimens or dried biological materials. Hence, using a paper bag is the most effective method to ensure the collected evidence remains uncontaminated and in the best condition for analysis.
