The structure and sizes of bones can be used by forensic scientists to identify unknown individuals. Different ethnic groups have different bone structures and there is stark contrast between the bones of males and females.
Forensic scientists can use a single bone - if that is all they are provided with - to calculate the height, gender, and ethnicity. I do not know how they can tell, since I have not studied in that area, but they can usually tell with first glance what gender it should be.
Also, different people have had unique medical records. Records of fractures, or breaks, or simply bone stress can help if forensic scientists see a certain feature (i.e, a fracture line).
The skull is probably the most important out of all the bones for identification. The skull can clearly show scientists what gender, age, ethnicity the person was. Even an untrained person can tell if they know what to look for. For example, males have a sharper brow and squarer jaw, while females have more rounded skulls. Teeth can help - especially if the scientist has access to dental records. The number and type of teeth in someone's mouth can tell you their approximate age and daily diet.
There was probably a lot of peripheral information in here, but I hope this helped!

How can you use karyotypes to identify a species?
Karyotypes can be used to identify species by examining the number, size, and shape of chromosomes in the cell. Each species has a characteristic karyotype that can be used as a unique identifier. By comparing the karyotype of an unknown sample to known species, scientists can determine the species of the sample.
How many species are unknown?
It is difficult to estimate the exact number of unknown species, but scientists believe that there are millions of species yet to be discovered, especially in unexplored regions like the deep sea and dense rainforests. Ongoing efforts in biodiversity research continue to uncover new species on a regular basis.
Are there useless animals on earth?
The most useless animal of the Earth is unknown. Scientists will have to do more research.
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.
What properties do scientists look for to identify an unknown substance?
Scientists look for properties such as density, boiling point, melting point, solubility, conductivity, and reactivity to help identify an unknown substance. By comparing these properties to known data in a database, scientists can often determine the identity of the unknown substance.
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.
How do forensic scientists use titration?
Forensic scientists may use titration to analyze chemical compounds found at crime scenes, such as drugs or poisons. By titrating a known substance with an unknown substance, they can determine the concentration or identity of the unknown substance. This information can then be used as evidence in criminal investigations.
How do you identify an organism with technology?
If an organism is very small, scientists use a microscope to try and identify it. In extreme cases, scientists can study the DNA of an unknown organism and compare it to a database to figure out what it is.
How do scientists identify unknown materials?
Scientists use a variety of techniques such as spectroscopy, chromatography, and microscopy to identify unknown materials. These methods involve analyzing the physical and chemical properties of the material to match them with known substances in databases or through comparison with reference samples. By comparing the data obtained from different techniques, scientists can determine the composition and characteristics of the unknown material.
When scientists are trying to identify an unknown organism they most likely consider what characteristic to determine its classification?
nucleas or the cell
How an scientists identify the composition of a compound?
Scientists can identify the composition of a compound through techniques such as mass spectrometry, nuclear magnetic resonance spectroscopy, and infrared spectroscopy. These methods help determine the elements present, their arrangement, and the functional groups within the compound. By comparing data from these analytical techniques with known compounds, scientists can identify the composition of an unknown compound.
Why do you think scientists can use basic properties of matter to help identify an unknown substannce?
Scientists can use basic properties of matter, such as melting point, boiling point, density, and solubility, to help identify an unknown substance because each substance has unique characteristics that can be compared to known values. By analyzing these properties and comparing them to known data, scientists can narrow down the possibilities and make an educated guess about the identity of the unknown substance.
When might it be helpful to identify an unknown element?
Identifying an unknown element is helpful in various scientific and industrial applications, such as determining the composition of a material, investigating pollution sources, or developing new technologies. It can also be crucial in fields like forensic science, environmental monitoring, and quality control.
What is the gender of they?
"They" is a gender-neutral pronoun that can be used for individuals who identify as non-binary, genderqueer, or genderfluid, or when the gender of the person is unknown or irrelevant.
What tools does a forensic scientist use?
Forensic scientists use a lot of computer technology, microscopes, and they draw what they see a lot. They also use kits for discovering finger prints, ultra violet lights or blacklights to see unknown substances on a scene (semen, saliva, blood)
