Forensic Science

Forensic scientists use various techniques to find fingerprints at crime scenes, such as dusting for prints with powder or using chemicals to reveal hidden prints. Once the prints are found, they are lifted and compared to known prints in a database for potential matches.

Compare the infra-red spectra of propan-1-ol and propan-2-ol. Both compounds contain exactly the same bonds. Both compounds have very similar troughs in the area around 3000 cm-1 - but compare them in the fingerprint region between 1500 and 500 cm-1.

The pattern in the fingerprint region is completely different and could therefore be used to identify the compound.

So . . . to positively identify an unknown compound, use its infra-red spectrum to identify what sort of compound it is by looking for specific bond absorptions. That might tell you, for example, that you had an alcohol because it contained an -OH group.

You would then compare the fingerprint region of its infra-red spectrum with known spectra measured under exactly the same conditions to find out which alcohol (or whatever) you had.

The loop fingerprint pattern is the most common type of fingerprint pattern, typically observed in about 60-70% of individuals. It is characterized by ridges that flow in one direction, recurve, and loop back on themselves.

PMI, or Post-mortem interval, is the time that has passed since a person died.

(Example: A body is found and it is suspected that it has been there for about two days. Two days is the PMI.)

Instars are developmental stages between molts in the life cycle of insects. Blowflies have three instar stages before they pupate into adults: first instar, second instar, and third instar. Each instar represents a different developmental stage with specific characteristics and requirements for growth and development.

The fundamental unit of heredity is the gene, which is a segment of DNA that contains the instructions for building and maintaining an organism's cells and processes. Genes are passed from parents to offspring and determine traits such as eye color, height, and susceptibility to certain diseases.

Evidence.

Police agencies now routinely use this so-called secretor system data to identify potential victims and criminals when blood samples are not available.

Short Tandem Repeats (STRs) are repeating sequences of 2-6 base pairs of DNA that are commonly used in forensic analysis for DNA profiling. These sequences vary between individuals and are highly polymorphic, making them useful for distinguishing one person's DNA from another's. STR analysis involves counting the number of repeats at specific loci to generate a unique genetic profile.

You can not change your fingerprint,this is how the police check for the criminal because it's impossible to change

Every human has Unique Fingerprint so than means No

They look at the structure of thebones and determine whether the body was dead of alive to begin with, when it was dumped. Then they look at the RBC's (red blood cells) and see how long the have been dead. Then they.....visit https://forensicfiles.com

Forensic scientists use various methods to identify people, including DNA analysis, fingerprint analysis, dental records comparison, and facial recognition technology. These techniques help in establishing the identity of individuals for legal and investigative purposes.

Forensic science and earth science both involve the application of scientific principles and techniques to understand and solve problems related to their respective fields. Both disciplines require attention to detail, data analysis, and critical thinking skills to draw conclusions and make interpretations based on evidence. Additionally, both sciences may involve fieldwork, lab work, and the use of specialized equipment and technology to gather and analyze data.

Linkage theory proposes that genetic traits are transmitted together because they are located close to each other on the same chromosome. This theory helped to establish the concept of genetic recombination and the understanding of genetic linkage mapping. It was an important development in the field of genetics.

The salary of a forensic scientist can vary depending on factors like experience, location, and employer. On average, a forensic scientist can make anywhere from $50,000 to $100,000 per year, which translates to roughly $4,000 to $8,300 per month.

Forensic biologists can earn an average salary of around $60,000 to $90,000 per year, depending on factors like experience, location, and employer. Salaries can vary based on the specific job responsibilities within the field of forensic biology.

To become a forensic biologist, you typically major in biology, forensic science, or a related field such as molecular biology or genetics. It is important to take courses in biology, chemistry, genetics, and forensic science to develop the necessary skills for this career. Internships or research opportunities in forensic labs can also be beneficial.

A pathologist is a medical doctor who specializes in diagnosing diseases by examining tissues, blood, and other body fluids. They analyze samples gathered during surgeries, autopsies, and other medical procedures to help determine the cause of illness or death and contribute to treatment plans.

Because every person has a unique number of variable number tandem repeats (VNTRs) or short tandem repeats (STRs). These sequences are non-coding DNA (doesn't code for a protein), the amount of repeats targeted on a specific chromosome can be analyzed and sorted out by length using gel electrophoresis (electric current used to separate DNA fragments by length).

If the a sample of DNA obtained from a crime scene was taken and amplified using polymerase chain reaction (PCR), multiple techniques could be performed on it. The VNTR/STRs of the sample DNA are compared to the DNA of the accused individual, if they have the same number of repeats then they are most likely guilty of the crime, but if the repeats differ by even one sequence, it cannot be assumed that the DNA definitely matches that person. These techniques help in forensic science, but a lot of accuracy in proof is needed before it can be used in a court case.

Paul Jeserich was a German gunsmith who contributed to the development of firearms by designing a breech-loading rifle in 1841. This design allowed for faster reloading compared to muzzle-loading firearms, leading to advancements in firearm technology. Jeserich's design laid the foundation for future breech-loading firearms.

The first thing a forensic scientist may look at to identify a deceased individual is any form of identification on the body, such as a driver's license, ID card, or medical alert bracelet. If no identification is present, the forensic scientist may use fingerprints, dental records, or DNA analysis to establish the person's identity.

The average salary for a forensic scientist in the United States ranges from $50,000 to $100,000 per year, depending on experience, location, and level of education. Entry-level positions may start lower, but with experience and specialization, forensic scientists can earn higher salaries.

The salary for a forensic scientist can vary depending on their experience, location, and employer. On average, in the United States, a forensic scientist can earn between $40,000 to $100,000 per year. In other countries, salaries may differ.

Forensic scientists can earn up to $100,000 to $150,000 per year, depending on factors like experience, location, and specific field of expertise. However, some professionals in leadership positions or with specialized skills can earn even higher salaries.
