Edmond Locard, a French forensic scientist, is credited with defining the principle of cross-transfer of evidence, stating that when two objects come into contact, there is an exchange of materials between them. This principle forms the basis of trace evidence analysis in forensic science.
What else can I help you with?
What type of molecule does the transforming principle contain?
The transforming principle contains DNA molecules. These molecules were identified by scientists Avery, MacLeod, and McCarty in 1944 as the substance responsible for the transfer of genetic information in bacterial cells.
What 2 organs are responsible for bringing oxygen into the body?
The two organs responsible for bringing oxygen into the body are the lungs and the cardiovascular system. The lungs extract oxygen from inhaled air and transfer it to the bloodstream, while the cardiovascular system circulates the oxygenated blood throughout the body to deliver it to cells.
Why is transfer of electron from 2s subshell to 1s subshell not possible?
Transfer of an electron from a higher energy orbit (2s) to a lower energy orbit (1s) is not possible because it would violate the energy conservation principle. Electrons naturally occupy the lowest available energy levels in an atom, following the Aufbau principle. This means electrons will only move to higher energy levels if they absorb energy, not by transferring between lower and higher energy levels.
What organisms are responsible for producing nitrogen compounds and what is this process called?
Decomposers are responsible for producing nitrogen compounds, This continual transfer of nitrogen from the non living part of the environment to the living part and back again is called the nitrogen cycle.
The molecule that contains an anticodon is?
transfer RNA or tRNA
What type of molecule does the transforming principle contain?
The transforming principle contains DNA molecules. These molecules were identified by scientists Avery, MacLeod, and McCarty in 1944 as the substance responsible for the transfer of genetic information in bacterial cells.
What is bertillon's principle of transference?
Bertillon's principle of transference refers to the belief that a person can unintentionally transfer physical evidence, such as fibers or hairs, between crime scenes through contact. This principle was developed by Alphonse Bertillon, a French forensic scientist, and has been an important concept in forensic science for linking suspects to crimes.
Which mode of transfer is mainly responsible for the transfer of heat in solid?
CONDUCTION
What are importance of Locard's principle of exchange in criminal investigation?
Locard's principle of exchange is important in criminal investigation because it states that every contact leaves a trace, allowing investigators to link suspects, victims, and crime scenes through the transfer of evidence. By identifying and analyzing these trace materials, investigators can reconstruct events, establish connections, and ultimately solve crimes. This principle emphasizes the significance of collecting, preserving, and analyzing physical evidence in criminal investigations.
What is Locards principle of exchange.?
Locard's principle of exchange states that every contact leaves a trace. This means that when two objects come into contact with each other, there will always be a transfer of material, such as fibers, hairs, or skin cells. This principle forms the basis for forensic science and is often used to link suspects to crime scenes through the analysis of trace evidence.
Which SI unit is named for scientist whose principle describe transfer of pressure in an enclosed fluid?
The SI unit that is named for the scientist whose principle described transfer of pressure in an enclosed fluid is pascal.
Which Si unit is named for the scientists whose principle describes transfer for pressure in an enclosed fluid?

Which si unit is named the scientist whose principle described transfer of pressure in an enclosed fluid?
The SI unit that is named for the scientist whose principle described transfer of pressure in an enclosed fluid is pascal.
What is Locard's principle?
When two objects come into contact there is always a transfer of material from each object to the other. Often this transfer is obvious, at least in one direction, but even the amount of material transferred, or its nature is such that nothing is visible. There is always some transfer.
Which SI unit is name for the scientist whose principle described transfer of pressure in an enclosed fluid?
The SI unit that is named for the scientist whose principle described transfer of pressure in an enclosed fluid is pascal.
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
What S1 unit named for the scientist whose principle described transfer of pressure in an enclosed fluid?
The Pascal (Pa) is the unit named for Blaise Pascal, the scientist whose principle described the transfer of pressure in an enclosed fluid.
