How do particles help forensic scientists?
Particles patterns help distinguish two different object even the two objects are of the same objects. For example, the soil in America and the soil in Asia, while both are soils, the particles of the 2 soils are different and help distinguish them. Same in forensic when distinguishing between soils, poisons, blood, contamination and even our DNA are made of particles and aredistinguish because different DNA has different particle arrangement.
What does forensic scientist have to do?
In order to be a Forensic Scientist there are various Forensic Sciences...

What are the cons of ballistics?
Some cons of ballistics include limitations in accuracy, particularly over long distances or in adverse weather conditions. Additionally, the study and analysis of ballistics can be complex and requires specialized knowledge and equipment. Finally, ballistic evidence can be affected by various external factors, such as the type of firearm used or the condition of the ammunition.
What are the advantages and disadvantages of ballistics in forensics?
One of the main advantages of ballistics in forensics is that it helps to narrow down which firearm was used in a crime. There are no disadvantages to using ballistics.
How was paraffin casting done?
I. Procedure of Paraffin Casting:
a. Heat the paraffin wax in a container until it melts. Allow cooling for a few minutes so that it will not burn the skin.
b. Let the subject wash his hands with water without using any soap or detergent. Wipe the hands of the subject with clean absorbent cotton.
c. Let the subject place his hands on a clean sheet of bond paper with the palms facing downward and the fingers closed together. Using a spoon or tong with cotton, pour the melted paraffin wax on the hands of the subject from the thumb and index fingers and the dorsal portion to the little finger side of the hands.
d. Cover the hands and fingers thoroughly with paraffin wax and place a thin layer of absorbent cotton to reinforce the wax.
e. Pour another layer of the wax until the absorbent cotton has totally absorbed the wax.
f. Allow the wax to cool and solidify before peeling them off.
g. When cool, direct the subject to move his fingers first and slowly moving his hands out from the casts.
h. Write on the bond paper the important identifications of the casted paraffin.
It appears that "maspectromator" is not a recognized term in the field of science or technology. It may be a misspelling or a combination of two separate terms. If you provide more context or clarification, I can try to help further.
What evidence does a forensic scientist give in court?
Forensic scientists provide expert testimony in court based on their analysis of physical evidence related to a crime. They may present their findings on fingerprints, DNA, ballistics, toxicology, or other scientific evidence to help establish facts or link a suspect to a crime scene. Their testimony is used to assist the judge and jury in reaching a verdict.
Why are bullets and casings found at different locations at a crime scene?
1 very basic reason:
How do forensic scientists find fingerprints using iodine?
Forensic scientists use iodine fuming to detect latent fingerprints by sublimating solid iodine crystals, which react with oils and fats on the skin. The iodine forms a visible brown color on the fingerprint ridges, making them easier to visualize and collect as evidence.
Why is evidence placed in a paper bag instead of a plastic bag?
Actually, some plastic bags contain "static electricity" that can/could remove or at the very least alter any evidence placed in the bag. Therefore, compromising the integrity of the "evidence" placed in it.
How does ballistics help police solve crimes?
Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared.
Knowing the trajectory of a bullet points you in the direction of its origination.
There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.
Where would a forensic anayst look to find a hooked process?
A forensic analyst would typically look in the operating system's process list or use forensic tools to identify any hooked processes. Hooking is a technique used to intercept function calls or events in a system, so identifying hooked processes can help in understanding potential tampering or malicious activity in a system.
How fibers help solve a crime?
Fibers found at a crime scene can provide valuable information such as the type of material, color, and potentially where it came from. By analyzing fibers, investigators can connect suspects to crime scenes or link different crime scenes together. This evidence can help establish a timeline of events and create a stronger case in court.
Who was the first person to apply the principle of forensic science to a working laboratory?
Dr. Edmond Locard, a French forensic scientist, is credited with being the first person to apply the principles of forensic science to a working laboratory setting. Locard also established the world's first forensic laboratory in Lyon, France in 1910.
How do you collect bullets in a crime scene?
Bullets are typically collected at a crime scene using evidence collection protocols such as wearing gloves, using proper tools like forceps or tweezers, and placing each bullet in a separate container to prevent cross-contamination. It is important to document and label each bullet with relevant information like location found and any identifying marks. Law enforcement should follow proper chain of custody procedures to ensure the integrity of the evidence.
Does a forensic scientist have benefits?
Yes! Of course a forensic scientist has benefits! Number one, they get paid a lot. Number two, they are the hero of an innocent person who is being accused. Other than that I'm not sure but i bet there's a lot more.

Yes, biology plays a vital role in forensic science. It helps in areas such as DNA analysis, toxicology, and entomology, which are crucial for solving crimes and identifying individuals. Understanding biological principles is essential for analyzing evidence and providing accurate conclusions in forensic investigations.
Who was the first person to apply the principles of forensic science to a working crime laboratory?
Edmond Locard was the first person to apply principles of forensic science to a working crime laboratory. He applied what is called the Locard's exchange principle to a working crime laboratory.
Are forensic scientist and forensic detective the same thing?
No, forensic scientists analyze physical evidence in a laboratory setting, while forensic detectives investigate crime scenes and gather evidence in the field. Both roles work together to solve crimes, with scientists providing analysis and detectives conducting investigations.
A Forensics Expert is anyone who is an expert int something that pertains to the court system. It is broadly used to refer to anyone involved in collecting evidence at the scene of a crime but can also refer to any expert involved in dealing with items recovered or relating to a crime.

How do you collect and label things from a crime scene?
Well the first thing they have to do is put on a forensic suit on so non of your finger print ect cross cross contaminate the evidence, you get a sterile police evidence bad pick it up with tweezers and put it in the bag then you sigh your name on the bag when any body else handles it they have to sigh it so people know that they have handled it
What are the two phases in a forensic scientist's analytical scheme?
The two phases in a forensic scientist's analytical scheme are identification and comparison. Identification involves determining the nature or category of evidence collected, while comparison involves comparing the evidence with known samples to establish possible links or associations.
How is white powder collected from a crime scene?
White powder found at a crime scene can be collected using a clean, dry tool such as a spoon, spatula, or brush. The powder should be carefully gathered and placed into a clean container, such as a paper bindle, to preserve any evidence for further analysis by forensic experts. Protective gear, like gloves and a mask, should be worn during collection to avoid contamination.
