Answer:

CODIS stands for Combined DNA Index Systems and is a computer program that stores the DNA Fingerprint of convicted criminals and missing persons. This program is very useful in forensic science.

Explanation:

CODIS is a computer program maintained by the FBI, which operates databases across the country. These databases contain more than five million profiles. CODIS covers several different indices.

CODIS uses algorithms to compare 13 different locations in STRs, plus one that determines the gender of the person in question. The system has rules and safeguards to protect the privacy of people in the database. Algorithms that point to positive results - which must be confirmed by an analyst - can provide clues to the police or even identify a possible criminal. The downside of using CODIS is that it only covers the profiles it includes - and there are over a million profiles waiting to be included in the system.

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which allows states to compare DNA information with one another.

Give two examples of stimuli that are conditioned reinforcers but not tokens. Explain why they are conditioned reinforcers, and
m_a_m_a [10]

The conditioned reinforcers known as tokens can be accumulated and traded for different reinforcers.

Any two suitable examples, such as a compliment, an invitation to dinner, the presence of a loved one, or a warm greeting are all suitable examples. These are all conditioned reinforcers since they are connected to stronger reinforcers. They cannot be accumulated and swapped for different backup reinforcers, hence they cannot be considered tokens.

What is backup reinforcer?

Backup reinforce is a reinforcer that serves as the foundation for a conditioned reinforcer. It is a reinforcer in a token system for which tokens can be traded in order to keep their reinforcing properties. For instance, poker chips can be converted into cash at the conclusion of a game of poker. The money serves as a secondary reinforcer in this situation. It is allowed to use any two relevant examples.
