Well first, he searches the forests for a lizard. Once he finds one, he grabs it and gets a sample of its DNA. He then sends it back to the science lab for positive identification. Hoped this helped, had to check a few different websites for the answer!

Performing the reagent tests last in the API 20E system helps to prevent cross-reactions between the other test results and thus ensure accurate identification of the microorganism based on its biochemical profile. It also helps to minimize the risk of false-positive or false-negative results that could occur if the reagents interact with the components of the other tests.
To perform a rabbit skin test for Corynebacterium, shave a small area of the rabbit's skin and inoculate it with the test sample. Monitor the site for any signs of irritation or redness, which could indicate a positive reaction to the presence of Corynebacterium. Repeat the test with a control substance to ensure accurate results.
A core sample of a mineral
I think you should resubmit this question as How long can you leave a sample in a desiccator? and it would help if you gave information about what sample you are putting in.

Sample B on the Mineral Identification Gizmo is calcite.
The acid-fast stain is positive in the sample.
A contaminated unknown sample could potentially introduce foreign material that may interfere with the identification process. This contamination could lead to misleading results or hinder the ability to correctly identify the unknown sample. It is important to ensure the sample is pure and free from contamination for accurate identification.
The acid-fast stain result is positive for the sample.
The acid-fast staining result for the sample is positive.
Sample E on the Mineral Identification Gizmo is Quartz. It has a hardness of 7 on the Mohs scale, a white streak, and breaks with a conchoidal fracture.
It usually takes 10 to 12 different restriction enzymes to produce a fragment pattern. This will allow positive identification of an individual.
I'm sorry, but I do not have access to specific tools or external platforms like Gizmo, so I cannot provide the mineral type for Sample H. However, mineral identification typically involves assessing properties such as color, hardness, luster, and streak. If you can provide more details about Sample H, I would be glad to help with the identification process.
It can have either a negative or positive trend
Mass spectroscopy can help identify the composition of a sample by measuring the mass-to-charge ratio of ions produced from the sample. This information can reveal the molecular structure and elements present in the sample, aiding in its identification.
