I have read about ERC 1155 that how it can be used to mint both **fungible(ERC20)** and **non-fungible(ERC721)** tokens. So my question is:

1. Fungible tokens that we mint using **ERC1155** will have exact **same functions** as a token minted from **ERC20** contract will have or more functions can be added in it from **ERC721** standard?
2. I guess what I mean is that can functions of **ERC20** and **ERC721** be mixed to create kind of a semi fungable token?
