peptidoglycan
Explanation:
Virtually all bacteria contain peptidoglycan in their cell walls; however, archaea and eukaryotes lack peptidoglycan. Various types of cell walls exist in the archaea. Therefore, the absence or presence of peptidoglycan is a distinguishing feature between the archaea and bacteria.

Hypoproteinemia is a condition of unusually low levels of plasma proteins. The problem is usually characterized by tissue edema.
What is edema?
Edema is the build up of fluid in the body's tissue. It occurs when tiny blood vessels in our body (capillaries) leak fluid. The fluid builds up in surrounding tissues, leading to swelling. Edema can affect anyone, but the condition most often affects people who are pregnant and adults who are 65 years or older.
There are four types of edema:
- Peripheral edema: This affects the feet, ankles, legs, hands, and arms.
- Pulmonary edema: This occurs when excess fluid collects in the lungs, making breathing difficult.
- Cerebral edema: This occurs in the brain.
- Macular edema: This is a serious complication of diabetic retinopathy.
