Forensic scientists are responsible for collecting and analyzing evidence at crime scenes, such as fingerprints, DNA, and bloodstains, in order to help law enforcement agencies solve crimes.

Astrology is not a scientific field and is not used in forensic science. Fingerprints, DNA, and ballistics are all common types of forensic evidence.

Dactylography is the process of identifying a person based on their unique fingerprint patterns. Fingerprinting is a more general term that can refer to the process of taking fingerprints or the study of fingerprints.

Trichology is the study of hair and fibers as forensic evidence. It can be used to identify a person, determine the time of death, or link a suspect to a crime scene.

Short tandem repeat (STR) analysis is the most common type of DNA analysis used in forensic science. It involves examining specific regions of DNA that are known to vary between individuals.

Toolmark analysis is the study of tool marks and impressions as forensic evidence. It can be used to identify the type of tool used to create a mark, as well as to link a suspect to a crime scene.

Ballistics is the study of firearms and ammunition as forensic evidence. It can be used to identify the type of firearm used to fire a bullet, as well as to link a suspect to a crime scene.

Bloodstain pattern analysis is the study of bloodstains and other bodily fluids as forensic evidence. It can be used to determine the direction and velocity of blood spatter, as well as to reconstruct the events of a crime.

Drug analysis is the study of drugs and controlled substances as forensic evidence. It can be used to identify the type of drug, as well as to determine the amount of drug present in a sample.

Trace evidence analysis is the study of trace evidence, such as fibers, hairs, and soil, as forensic evidence. It can be used to link a suspect to a crime scene or to identify a victim.

Dactylography is the study of fingerprints as forensic evidence. It involves the analysis of fingerprint patterns to identify individuals.

Ballistics is the study of firearms and ammunition as forensic evidence. It involves the analysis of firearms and ammunition to determine their characteristics and to link them to crime scenes.

Bloodstain pattern analysis is the study of bloodstains and other bodily fluids as forensic evidence. It involves the analysis of bloodstains to determine the direction and velocity of blood spatter, as well as to reconstruct the events of a crime.

Drug analysis is the study of drugs and controlled substances as forensic evidence. It involves the analysis of drugs to identify their composition and to determine their effects.

Trace evidence analysis is the study of trace evidence, such as fibers, hairs, and soil, as forensic evidence. It involves the analysis of trace evidence to determine its composition and to link it to crime scenes.
