What are the functions of intrinsic proteins in animal cell membranes and key characteristics of Basidiomycota organisms?

here are the answers to the questions from the image.

1. Intrinsic proteins present in the cell membrane of animal cells function mainly as:
Intrinsic proteins are embedded within the cell membrane and perform various crucial roles. These include acting as enzymes, transport proteins (channels and pores), and receptor molecules for cell signaling. Among the given options, receptor molecules are a primary function, enabling cells to receive and respond to external signals, which is fundamental for cell communication and regulation.

• B. Receptor molecule

2. Organisms in the phylum Basidiomycota such as mushrooms possess:
Basidiomycota, which include mushrooms, are characterized by having septate hyphae. These are hyphae divided by cross-
