The statement 'interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane' explains why protein folding is critical. This process is fundamental for the function of transmembrane proteins.
Protein folding refers to the process by which a polypeptide (i.e., a protein) adopts its final tridimensional 3D shape (conformation).
In a protein, some amino acids contain hydrophilic R groups, whereas other amino acids contain hydrophobic R groups.
During protein folding, hydrophobic amino acids are arranged so they can interact with the long chains of the fatty acids in the internal region of the lipid bilayer, whereas hydrophilic amino acids are arranged so they interact with water on the surface of the cell membrane.

Attached is Model 1. I found the exercise on the internet.
A. The portion of the molecule that's polar is the head of the molecule - phosphorus containing group plus the glycerol backbone.
The other part of the molecule has two fatty acid chains which are hydrophobic meaning that they are nonpolar.
B. Yes, it would mix well with water because polar molecules are dissolved in water perfectly. Their partly positive portion and their negative polar connect to the positive charge of the H atoms and negative charge of the O atom of the water molecules.

D

Brain can create new connection between neurons.
The answer to your question is fat digestion!!
The answer is the third one. Rice would provide everyone with food but would not allow for all the needed nutrients to be absorbed. Rice is a starch or carb and that's the only compound you would be getting. Your body would then lack other nutrients like protein, and calcium that allow your body to grow and develop properly.
