I'm assuming you mean nails that you hammer in, not fingernails. They're thin on one end so that they are hammered in more easily, because when you apply force to an object and the object has a small surface area (such as the end of a nail) that force is exerted on a tiny area, thus goes in more than if you applied the same pressure on a larger surface area, for the force would just 'spread out' equally. And further it's thicker because then there's more grip, it's stronger etc.
id think nails (that holds wood and stuff together), rust, and other stuff like that
because one end is pointed so the way it goes through the wood and the other end is flat because that way the hammer can hit it too go into the wood or what ever else your putting it into that is why the nails are madevery sharp at one end thicker than the other end other end

Iron is a magnetic metal.
Sure; nails are usually made from some metal, and all metals are conductors.
For finger nails :no,the other nails are iron , copper, etc but not plastic
Nails were historically made of iron by a local blacksmith. Nowadays, most nails are usually made in factories from steel wire, although they could also be made of aluminium, brass, or many other metals.
Carpet nails are generally made of mild steel.
iron nails are nails made up of iron
Finger nails are made of a protein called keratin.
Some nails are made of copper or brass. Also, some nails are galvanized to protect them from rust. There are also aluminum nails--they're used with vinyl siding and aluminum trim coil.
Hair and nails are made primarily of calcium.
Yes
Finger nails (and toe nails) are made of keratin.
Normally nails aren't made of an alloy however they are galvanized, this means they have a coating of a less reactive metal such as Zinc as to prevent rusting of the nails. Nails are normally made out of iron.
Nails are NOT made out of cartilage. Nails are made out of keratin, the same structural component that makes up hair. Both keratin and cartilage are types of structural proteins, but they are not related.
What hair and nails have in common is that they grow. A hair and nails what they have in command is that they are the same as dogs.
