yes it can as its outside edges stick out of the phospholipid bilayer exposing it to the watery environment (polar/hydrophilic) and part of the protein is inside the bilayer along with the phospholipid tails (hydrophobic/nonpolar).
yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.
They are usually transmembrane proteins.
The cell membranes that can act as channels are called integral proteins. Peripheral proteins are the ones that are attached to just one side of the cell membrane.
The carrier proteins that aid in facilitated diffusion are integral membrane proteins. These proteins are embedded within the cell membrane and undergo conformational changes to transport molecules across the membrane.
Because the heads of the phospholipids are hydrophilic (water loving) and the tails of the phospholipids are hydrophobic (water hating). The tails are pointing towards each other and the heads are facing the membranes.

An integral protein must be firmly embedded within a cell membrane, spanning across it from one side to the other. This positioning allows integral proteins to have both an extracellular and intracellular domain, contributing to their crucial role in cell signaling and transport.
In order to be an integral membrane protein, a protein must have hydrophobic regions that can interact with the hydrophobic lipid bilayer of the cell membrane. These proteins are embedded within the membrane rather than just associated with the membrane surface.
Integral proteins can be receptors, but not all integral proteins are. Therefore you cannot use the terms integral and receptor interchangeably. Integral proteins are proteins that are permanently attached to the membrane, and span the width (go from one side to the other). Receptor proteins are found on the surface of a cell and receive signals from other cells or the environment.
Skim milk is not considered amphipathic. Amphipathic molecules possess both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions, which allows them to interact with both water and lipids. While skim milk contains water and dissolved proteins, it primarily consists of water, lactose, and milk proteins, without the distinct dual nature of amphipathic molecules.

Another name for integral proteins is integral membrane proteins.Most are transmembrane proteins, which span the entire depth of the membrane.
The carrier proteins that aid in facilitated diffusion are integral membrane proteins. These proteins are embedded within the cell membrane and undergo conformational changes to transport molecules across the membrane.

Integral proteins.
Proteins are often synthesized by ribosomes on the rough Endoplasmic Reticulum.
