Mid-term Exam Practice - A2 Forensic Science

The given correct answer is "Yes - Locard's Exchange Principle". Locard's Exchange Principle states that when two objects come into contact, there is always a transfer of materials between them. This principle is commonly applied in forensic science to analyze evidence left at a crime scene. In the context of the question, if two objects collide and particles from both are left on each other, it aligns with Locard's Exchange Principle as there is a transfer of particles between the objects during the collision.

Forensics is the study and practice of applying scientific methods and techniques to the legal system. It involves the collection, analysis, and interpretation of physical evidence in order to investigate and solve crimes. By using scientific principles and methods, forensics helps to uncover the truth and provide evidence in legal proceedings.

Select the answer that includes the last name of both individuals described in the question above

Albert Osborn developed the fundamental principles of document authenticity evaluation.

Calvin Goddard was the first to use a comparison microscope to link a bullet to a gun scientifically. This means that he developed a method to examine and compare the markings on a bullet with those on a gun, allowing for the identification of the specific gun that fired the bullet. This breakthrough in forensic ballistics greatly advanced the field of criminal investigation and helped establish the connection between firearms and their use in crimes.

Alphonse Bertillon developed the first systematic means of personal identification. He created a method known as anthropometry, which involved taking precise measurements of various body parts to create a unique profile for each individual. This system was widely used in the late 19th and early 20th centuries and was instrumental in the field of criminal identification. Bertillon's method was eventually replaced by fingerprinting, but his contributions to the field of forensic science were significant.

Walter McCrone is the correct answer because he was a renowned microscopist and analytical chemist who extensively used microscopy and other analytical techniques to examine evidence. He is particularly known for his work in forensic science, where he applied microscopy to analyze various types of evidence, including paint, fibers, and questioned documents. McCrone's expertise and contributions in the field of microscopy make him the most appropriate choice for the individual who first utilized this method to examine evidence.

Francis Galton was the first to study and publish work suggesting fingerprints as an effective means of personal identification. He conducted extensive research on fingerprints and developed a classification system that is still widely used today. Galton's work laid the foundation for the use of fingerprints in forensic science and the identification of individuals based on their unique patterns.

Mathieu Orfila is considered the father of forensic toxicology because he was the first to apply scientific principles to the field. He published the first comprehensive book on the subject, "Traité des poisons," in 1814, which laid the foundation for modern toxicology. Orfila's work involved studying the effects of poisons on the human body and developing methods to detect and analyze them. His contributions helped establish toxicology as a distinct discipline within forensic science, making him a pioneer in the field.

Leon Lattes is the correct answer because he was the first to develop an effective method of determining blood type from dried up blood stains and splatter. His method, known as the Lattes method, involved using antibodies to determine the presence of specific blood types. This breakthrough in forensic science allowed investigators to identify blood samples at crime scenes, providing valuable evidence in criminal investigations.
