2 . What are individual characteristics? Give an example of an individual characteristic?
Individual attributes are homes associated with one common source into a high amount of certainty. An example of individual attributes that forensic scientists may possibly look for would be the ridge qualities of two fingerprint selections.
3. What is the difference among individual characteristics and category characteristics?
Class qualities are the ones that can only be associated with organizations not just a one source
4. What happen to be physical and chemical properties? Give among the each. Physical properties are those that identify a material or object without mentioning any other element.

Chemical homes are those that describe what goes on when a element reacts with another element. For example , if the drug heroin comes into contact with the Marquis reagent chemical it turns purple. This behavior explains the chemical property of heroin helping forensic scientists identify the presence.
a few. What do forensic researchers do to gather and preserve soil samples? Soil examples are typically accumulated from the criminal offense scene in a 100-yard radius at different spots. Forensic scientists consider great treatment in collecting and preserving soil trials, if garden soil is found on the bottom of a sneaker for example the soil is left on the boot and the complete shoe is taken to the crime lab.

If they happen to be less attentive of this then it might not be any use to these people and just certainly be a waste of their time.

I really believe that the most beneficial evidence is usually physical evidence because it assists give greater detail than any other type of data.
three or more. Why do you think that forensic scientists carry on and look for category characteristics presented their limitations?
Forensic scientist might continue to look for class qualities because they will like more evidence to convict or perhaps help with other law capturing reasons.
4. What do you think can be some of the difficulties in collecting and protecting impressions? Why?

5. If you were on a court, do you think you should expect person characteristics in the evidence? How come or why not? What results might it have in the event that individuals have individuals features presented? I believe I would anticipate individual features because that would help me produce some severe and maybe even final decisions.
