A= A hydrogen bond forms between two polar side chains.
B= A hydrogen bond from between a polar side chain and protein back bone.
D = hydrogen bond form between polar side chains and a buried water molecules.
All these are use to accommodate the polar amino acid.

The answer is: False.
Why?
It's known that most common galaxies are spiral - shaped, but according to some studies, the irregular - shaped galaxies can not be even considered "spiral shaped".
Irregular - shaped are galaxies defined by their lack of structures, and they were formed by an external gravitonal force acting, in fact, it's believed that they were spiral or elliptical galaxies before.
An example of irregular - shaped galaxies is Small Magenallic Cloud.
Have a nice day!
