Most Archaeans lack a ______ cell wall.

Biology
1 answer:
Morgarella [4.7K]3 years ago
6 0
Most Archaens lack peptidoglycan<em> </em>a.k.a murein in their cell wall. Peptidoglycans help maintain the strength of the cell wall as well as repel the osmotic pressure in the cytoplasm. A common misconception of the use of peptidoglycans is that it gives the cell shape. However, peptidoglycans only improve the structure of the cell wall by strengthening it.

Hormones can alter the amount of water reabsorbed during urine production, allowing the production of either concentrated or dil
Sedaia [141]

The amount of water reabsorbed during the formation of urine can be changed by hormones, enabling the creation of either concentrated or diluted urine. The duct serves this purpose.

In heating, ventilation, and air conditioning (HVAC), air is delivered and removed by ducts, which are conduits or passageways. Examples of the necessary airflows include supply air, return air, and exhaust air.  As part of the supply air, ducts frequently deliver ventilation air as well. As a result, air ducts are one way to guarantee both thermal comfort and adequate interior air quality. The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated. The body makes less pee when its ADH level is high. A low
