Why our fingerprints are unique

Why our fingerprints are unique.

Did you ever think about why our fingerprints are unique or non identical,even identical twins have different fingerprints.

The reason lies partly in their genes, but mostly from the unique way everyone skin grows before birth. The reason fingerprints are unique is the same reason individual humans are unique.There is no single cause for unique fingerprint design.Instead it's the result of both your genes and your environment.This is called multifactorial inheritance.

look closely at the lines on your fingertips these are called friction ridges, the reason for fingerprint is grip to hold or handle things. Fingerprint impression left Behind when your fingers touch glass or when you put ink on your fingers and press them on a piece of paper ,friction ridges grow different designs like arches or whorls. If a parent fingerprint patterns have arches more likely you have it too.That have a possibilities but never likely to be a identical fingerprint.Fingerprint pattern only matches your parents or your identical twin, not fingerprint.Because you are unique so that your fingerprints are also unique. Why do you have a same like pattern from your parents is from your generic data genes are like instructions written inside the body.They give directions things like eye color, nose shape and more

Genes also tell the skin how and when to grow.Before a baby is born they grow as a fetus inside mother's womb. The dermis and epidermis grow together.Friction ridges appear where these layers meet,guided by genes. But these layers don't grow at the same speed for every fetus. If one layer of cells grows faster, it can stretch and pull the others.As the fetus moves, their fingers can rub against the side of the womb. These tiny forces push the skin as it grows.Together ,they mold the direction of the growing ridges.

The result is a unique fingerprint unlike anyone else’s fingerprints. Everyone’s skin grows in a slightly different environment.That’s why it’s so unlikely anyone has the same fingerprints as you.

Interstellar Movie Mann's planet Frozen clouds explained

In the movie when the crew descend to Mann's planet the ranger scrap the edge of an ice clouds. These clouds are largely frozen "Dry ice"(solid form of carbon-di-oxide) the reason why Mann's planet is too cold is, it orbiting the gargantua(black hole) at an over elongated path, the planet swings close(inward journey) around the gargantua and flies out to a large distance(outward journey) and come close around and flies out again, In the movie when the crew desecend to land Endurance is at extreme end of the orbit (outward journey) and after docking scene endurance comes closer to the gargantua; it shows that the Mann's planet mostly away from the accretion disk of gargantua; oribtary of Mann's planet around gargantua Mann's planet is cold and ...

How to calculate age of tree using ring without cutting

How to calculate age of tree using ring without cutting The rings in the trees are used to calculating the age of the trees and tells what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The color and width of tree rings can provide snapshots of past climate conditions. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years Calculating the age of the tree without cutting The age of the tree can be calculated without cutting the tree with the help of an instrument called Increment borer this instrument is bored into the tree up to the centre and ...
