How do forensic scientists analyze unknown powders?
Forensic labs are often called in to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances: Presumptive tests (such as color tests) give only an indication of which type of substance is present -- but they can't specifically identify the substance. Confirmatory tests (such as gas chromatography/mass spectrometry) are more specific and can determine the precise identity of the substance.
List two things that line graphs allow scientists to do?
They allow scientist to identify trends and make predictions
What two groups of bacteria are you trying to identify when doing a mannitol galatinase and lipase tests?
Pathogenic and non-pathogenic Staphylococcus species.
Identify two advantages of mining minerals?
Mining minerals has way more than two advantages, but since you asked for 2, they create jobs (for miners) and not to mention the countless uses of the atual minerals and profits.
what is forensic drug testing?
Forensic drug testing is to identify unknown powders, liquids and pills that may be illicit drugs. There are basically two categories of forensic tests used to analyze drugs and other unknown substances. They are Presumptive tests and Confirmatory tests.
What are two ways you can identify a physical property?
You can identify a physical property by observing and measuring characteristics such as color, shape, size, or density. Another way is to perform various tests or experiments to determine properties like melting point, boiling point, or conductivity.
Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
Two gram negative bacilli that produce swarming colonies What biochemical tests would you use to identify the bacilli?
Given that the two species of swarming gram negative bacilli are Proteus vulgaris and Proteus mirabilis, one must find the tests that differentiate these two organisms. Referencing the Textbook of Diagnostic Microbiology by Mahon, Lehman, and Manuselis, I've found the two major differences are their reactions to citrate and sucrose.One can use automation or strip testing to discover the organisms reactions to these substances.
How could you identify two unknown white crystals such as salt and sugar?
If you can isolate the compound individually first, that's the best thing. Further to this, anion and cation tests will tell you what kind of salt it is. There are also tests to determine simple sugars.
In computer terms what are two communication tests which are needed on your system and why?
Two important communication tests for a computer system are network connectivity tests and latency tests. Network connectivity tests ensure that the system can successfully send and receive data over the network, verifying if the devices can communicate correctly. Latency tests measure the time it takes for data packets to travel between two points, which is crucial for assessing the performance of real-time applications like video conferencing or online gaming. Both tests help identify potential issues that could affect overall system performance and user experience.
