  • At what age does bone density reach a peak (20s)

  • 32 teeth still intact, skeleton belongs to which age group (adult)

  • Inhalation of large amounts of hydrogen cyanide is fatal in less than how many minute(s) (idk, options are 1, 2, 3, 4 minutes) *I think its 3 minutes?

  • Blood alcohol is how many times bigger than breath alcohol number (2300)

  • What concentration of blood alcohol is fatal (35%)

  • Heavy metal exposure cause blue discoloration (lead)

  • Study of drugs, poison, toxins, metabolites (toxicology) 

  • Most important specimen in postmortem toxicology (vitreous humor)

  • ED50 (produce pain relief for 50% of the population )

  • When does the surface of the eyes dry out (4-6hrs )

  • fracture of hyroid bone (ligature/manual strangulation)

  • Applied physical force exceeds tensile strength of tissue to what force (Blunt Force)

  • Permanent, fixed point of reference in outdoor crime (datum point)

  • Second priority after security in crime scene investigation (preservation of evidence)

  • ABO blood type can be categorized as what kind of evidence (class)

  • Anthropologist that used skeletal remains of victim in court (Clyde snow)

  • Issuing death certificate ( medical examiner)

  • Study of hair with marcelle lambert (victor balthazard)

  • Era where forensics began as modern form of discipline (1900s)

  • when a person loses significant amount of blood dies by bleeding to death (exsanguination) 

  • Key applications of behavioral science in forensic sciences EXCEPT (truthfulness)

  • In blunt-force trauma, a damage to bone will leave telltale marks known as a: (wel..)

  • Under what medical condition can excessive water intake in athletes lead to coma and death? (Hyponatremia, also known as water intoxication)

    • cause seizures, brain damage, a coma, and even death

    • Drinking too much water can increase the pressure inside the skull. This can cause various symptoms and, in severe cases, become fatal.

  • To determine actual blood alcohol concentration (use chromatography)

  • The most common presumptive test for blood identification uses the indicator: (Phenolpthalein)

  • DNA samples are analyzed using an instrument that combines a separator unit and a detector. The separation is accomplished using a technique called: (denaturation)

  • Empty gastric/stomach contents into small intestine takes (6-8 hrs)

  • VICAP - national FBI database of violent crimes, used to compare new cases to previous ones to cross-investigate behavioral patterns

  • dental configuration 2:1:2 (children) 

    • 2:1:2:3(adults) in each quadrant: two incisors, one canine, two premolars, and three molar, for a total of 32 adult teeth

  • Identical copies of DNA during replication: amplicon

  • Kary Mullís received a Nobel Prize in chemistry in 1993, for his invention of the polymerase chain reaction (PCR)

  • Fly specks mistaken for blood spatters

  • Bertillon and the photos he took of convicts (behind the concept of mugshots)

  • Hard, smooth, and non-porous will create little to no spatter 

  • Photo imaging: means the process that automatically scans an individual's facial features and produces a facial image. The image is added to the statewide SFIS database. (Probably refers to the 3D photos with light adjustments) 

  • Oldest stage of blow flies in chest, younger flies and maggots in the orifices (what is the pattern): I think it’s the fact that there was a wound in the chest (they were attracted to that first) but it could be that there was a fresh wound(explains the new maggots) orrr the body was recently moved attracting the flies to a new area 

  • Guilty but didn’t know what they had done rule (1960s)

  • GS/MS (gas spectroscopy/mass spectrometry): first step- Samples are generally dissolved or diluted in a solvent

  • Gas spectrometry - separates chemical into smaller components, produces visual results for analysis

  • Sir Arthur Conan Doyle - author of Sherlock Holmes (elp…)

  • Uppers - another name for stimulants

  • Direction of bloodstain - look at tail to determine which direction the blood came from
