Question and answer
what is the difference between a crime scene investigator and an Arson investigator?
Arson investigators are law enforcement officials who are responsible for verifying the cause of a fire that resulted in property damage, injury or death. CSI handles more complex crime scenes, such as homicides, sexual offenses, and robberies.

Combustion is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.

please give an example of a crime scene that would include combustion?
Weegy: Be thinking about the probable location where the fire may have started. If arson was the cause, several points of origin may be noted. Note any odors present that may indicate the presence of accelerants. [ The arson investigator’s search for traces of flammable liquid residues may be aided by the use of a highly sensitive portable vapor detector or “sniffer” (See Below)). This device can rapidly screen suspect materials for the presence of volatile residues by sucking in the air surrounding the questioned sample. The air is passed over a heated filament. If a combustible vapor is present, it oxidizes and immediately increases the temperature of the filament. The rise in filament temperature is then registered as a deflection on the detector’s meter. Such a device is not a conclusive test for a flammable vapor, but it does provide the investigator with an excellent screening device for checking suspect samples at the fire scene.

Define sustainability and sustanable development.
Weegy: Sustainability is the capacity to endure. [ For humans, sustainability is the long-term maintenance of well being, which has environmental, economic, and social dimensions, and encompasses the concept of stewardship, the responsible management of resource use. In ecology, sustainability describes how biological systems remain diverse and productive over time, a necessary precondition for human well-being. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. Sustainable development (SD) is a pattern of resource use, that aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come (sometimes taught as ELF-Environment, Local people, Future). The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs. ] (More)
