Peptidoglycan is present in the cell wall of gram-positive bacteria. Bacteria are safeguarded by a robust cell wall comprising peptidoglycan. The layer of peptidoglycan in the cell wall of bacteria refers to a crystal lattice composition produced from linear chains of two alternating amino sugars, that is NAM (N-acetylmuramic acid) and NAG (N-acetylglucosamine). Peptidoglycans is one of the most essential sources of D-amino acids in nature.
Answer:
The outside of the ear, commonly referred to as just <em>the ear</em>.
Explanation:
The ear is the organ that allows us to hear things around us. To mammals, including humans, it's also the organ that gives balance.
Although it may seem like a simple organ, the ear has a very complex anatomy. It has three main parts: the outer, middle, and inner ear. All of them are made up of multiple smaller structures.
The pinna (also called the auricle) is one of the parts of the outer ear. It is the outside part of the ear, which we commonly refer to as just <em>the ear.</em>
