What is the function of the ridges on your fingers which create fingerprints?
Fingerprints are formed by the ridges on our fingers to improve our grip and enhance tactile sensitivity. They also help with grasping objects and provide friction to prevent objects from slipping out of our hands. Additionally, fingerprints aid in enhancing our sense of touch and are unique to each individual, making them useful for identification purposes.
What is the difference between gyri and sulci?
Parts of the Brain: Cerebrum-largest part of brain, 7/8 total mass of the brain. * 2 cerebral hemispheres: # ridges- gyri # grooves- sulci *Gyrus(gyri)-is a ridge on the cerebral cortex. Folds on the brain material. Many ridgescalled convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum's surface. *Sulcus(sulci)-shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure.
What causes fingerprints?
Basically, a fingerprint left on a surface is caused because: Oils form on sweat glands in our fingers, collecting on ridges of a fingerprint. After touching something, the oils and other materials previously on the ridges are left behind on the surface you just touched. I hope that helps.

What are the metal ridges between the spiral grooves on the inside of a rifle barrel?
The metal ridges between the spiral grooves on the inside of a rifle barrel are called lands. They are part of the rifling, which imparts a spin to the bullet as it travels down the barrel, enhancing accuracy and stability in flight. The grooves are the recessed areas that help guide the bullet, while the lands engage the bullet, ensuring a tight fit and promoting a more consistent trajectory. Together, lands and grooves are essential for improving the performance of a firearm.
