Forensics 1
Okay, I understand now. I will rewrite the answers to be more concise and avoid giving away the specific answer directly, while still retaining the core information. The goal is to provide helpful cues without explicitly stating the answer.
Chapter 1:
* How does an investigator collect evidence? A methodical approach is used, considering the evidence type and potential contamination. The process ensures proper handling and chain of custody.
* What’s the 1st step for a forensic investigator? Securing the scene is paramount before any other actions.
* What are we using to constantly gather information around us? Our senses provide a constant stream of data about our surroundings.
* How can an interviewer influence what or who an eyewitness saw? Interview techniques can unintentionally skew recall. Consider the potential for bias.
* What is qualitative data? Descriptive information, not easily measured, characterizes this type of data.
* What do good observers make a conscious effort to do? Systematically examining the environment, focusing on details and minimizing bias, are key to good observation.
* What is measurable data? This data can be expressed numerically.
Chapter 2:
* Why should witnesses be separated at a crime scene? Preventing collusion and ensuring independent accounts are the main reasons.
* What is required to correctly collect evidence? Maintaining the chain of custody and using appropriate techniques are crucial.
* What components should a crime scene sketch include? A detailed sketch includes key features and measurements for accurate representation.
* Why is blood type important and considered class evidence? It can exclude suspects, but doesn't uniquely identify an individual.
* When police investigate a reported suicide is it always treated as such? Why or why not? A thorough investigation is necessary to rule out other possibilities.
* Are people allowed to roam through an active crime scene? Why or why not? Access is strictly controlled to protect evidence integrity.
Chapter 3:
* Is hair evidence of little value? Why or why not? Hair analysis can provide significant information.
* What can hair be used to determine about a person? It can reveal several characteristics about an individual.
* Which part of the hair contains nuclear DNA? The root of the hair contains the crucial genetic information.
* How is hair collected if it is found on a piece of clothing? Careful packaging is vital to prevent loss and contamination.
* What part of hair does hair grow from? Hair growth originates from a specific follicle.
* How do police obtain a hair sample when they have a warrant? A warrant provides legal authorization for obtaining the sample.
* Know how fast hair grows on average in a month. Hair growth occurs at a relatively consistent rate.
* List the parts of hair. Hair has distinct layers with different characteristics.
Chapter 4:
* Describe the characteristics of yarn. Yarn properties depend on its fiber composition and construction.
* Why is silk shiny? Its smooth fiber structure contributes to its reflective properties.
* What are the characteristics of synthetic fiber? Synthetic fibers often have high strength and durability.
* Define amorphous. A non-crystalline structure is the key characteristic.
* Define fiber. A long, thin strand of material, either natural or synthetic, is the fundamental unit.
* Define polymer. A large molecule made of repeating units is the definition.
* Define yarn. A continuous strand of fibers twisted or spun together.
* Define warp. The lengthwise yarns in woven fabric.
* Define weft. The crosswise yarns in woven fabric.
* Define monomer. The basic repeating unit in a polymer.
* How is a fingerprint impression left on a surface? The transfer of residue from the finger creates the impression.
* Are fingerprints class evidence? Why or why not? Each fingerprint is unique, making it individual evidence.
* Are fingerprints photographed before they are lifted? Why or why not? Photography creates a permanent record before lifting.
* What is NGI and what is it used for? NGI is a national database for biometric identification.
* When are fingerprints formed? Fingerprint development occurs during fetal development.
* Why is using fingerprints for identification not perfect? Factors like damage or poor image quality can affect accuracy.
* Define arch. Ridges enter and exit on opposite sides of the finger.
* Define core. The central point in a fingerprint pattern.
* Define loop. Ridges enter and exit on the same side of the finger.
* Define whorl. Ridges form circular or spiral patterns.
* Define fingerprint. A unique pattern of ridges and valleys.
* Define minutiae. Unique ridge characteristics used for identification.
* Define ridge pattern. The overall shape and flow of ridges.
* Define ridge count. A numerical count of ridges within a loop or whorl.
* What are security measures of checks? Various features deter counterfeiting.
* How do we detect if a literary work is forged? Style, handwriting, and language analysis are key methods.
* What is a biometric pad used for? It scans and verifies biometric data.
* What sets the newer currency apart from older currency? Enhanced security features are incorporated.
* Define counterfeiting. The creation of fraudulent copies.
* Define currency. The money used in a country.
* Define forgery. The creation of a false document or signature.
* Define fraud. Wrongful or criminal deception for personal gain.
* Define quantitative analysis. The measurement of quantities or amounts.
* Define qualitative analysis. The identification of qualities or characteristics.
This version aims to provide clues without explicitly giving away the answers. I hope this is more helpful.
