What else can I help you with?
What two things do fingerprints consist of'?
Fingerprints consist of ridge patterns and skin ridges. The ridges create unique patterns that are used for identification purposes.
Fingerprints are caused by?
Finger prints are made by dermal ridges on the fingers. You also have much larger ridges on the palms of the hand. They prevent slipping while you are holding on to things.
What causes fingerprints to be left behind when people touch things?
Fingerprints are left behind when people touch things due to the sweat and oils present on the ridges of their fingers. These residues get transferred onto surfaces, creating a pattern unique to each individual.
Purpose of Fingerprints?
Fingerprints are unique patterns of ridges and valleys on the skin of an individual's fingers. They serve as a means of identification because each person has a distinct set of fingerprints. Law enforcement agencies use fingerprints to identify suspects or victims and exclude or confirm individuals from investigation.
Why do you have fingerprints?
We have fingerprints because it provides a grip. If your finger tips were smooth it would be harder to grip things. The exact pattern is unique to each individual, although there are standard configurations.
Why do your fingers have friction ridges?
Your fingers have friction ridges so that we can grab or catch or even hold things with our fingers. If we did not have these friction ridges then probably we wouldn't be able to hold things without the help of our fingers.
Without fingerprints what would happen?
we would not be able to hold things proply and people would not be able to be identifid with fingerprints
What are those curly things inside the brain?
These are the gyri (ridges or bumps) and sulci (furrows between the ridges). Certain patterns of gyri and sulci are common to all humans and are associated with certain functions. Many animals, especially those with large brains have gyri and sulci also.
Why are fingerprints left on things you touch?
The oils and dirt on your skin stick to items that you touch. This causes fingerprints to form on most items.
How are elements like fingerprints?
Each element has an unique set of attributes, just like fingerprints. One of the most common attributes of elements used is its spectral signature. When an element is excited, it emits photons on specific frequencies. These frequencies can then be used to map things such as the chemical composition of distant exo-planet atmospheres or moons, such as Titan.
What is the measurement of things such as fingerprints and retinal scans used for security access?
biometrics
What are fingerprint's?
Variation in humans is the pattern of ridges in the skin of the finger prints.However, fingerprints are used to hold on to things. They were not actually made to ID people. We just have come up with this ID when we realized that no two people have the same finger prints. We have used other methods to ID, including DNA tests and retinal scans.
