What element is found in egg yolks and hair?

The element found in both egg yolks and hair is sulfur.

Here's why:

* Egg Yolks: Sulfur is a component of the amino acid methionine, which is abundant in egg yolks. Methionine is crucial for protein synthesis and other bodily functions.

* Hair: Sulfur is a key component of the amino acid cysteine, which is a building block for the protein keratin. Keratin is the primary protein that makes up hair, skin, and nails.

Therefore, sulfur plays a significant role in both the structure and function of egg yolks and hair.
