Answer:
A cell membrane is made of two layers.
The cell membrane is composed by a phospholipid bilayer where the interior side is hydrophobic and non-polar, while the outside is hydrophilic and polar
Pores and proteins in the cell membrane allow passage through it.
The pores and proteins in the cell membrane have several functions such as, for example, cell signaling (proteins) and selective transport (pores)
One fourth means (one half) of (one half) .
So the 18 months must be two half-lifes.
The half-life of this particular isotope is 9 months.
- How do the organisms get energy from the deep-sea vents?
- How are the organisms able to live under the water pressure?
- Are the organisms mostly producers or consumers?
Answer:
c.Hypotension indicates good health
Distention from accumulating gas and fluid impede venous return, leading to bowel wall ischemia.
<u>Explanation:</u>
When the bowel lumen is obstructed, the gases and fuids starts accumulating as a repose to the obstruction. The accumulated fluid and gases results in the swelling or enlargement. This will result in the production of electrolytes and water inside the mumen that is in obstruction. The wall of the bowle will also enlarge and becomes swollen.
As more and more fluid and gas gets accumulated in the bowel, the bowel wall will be enlarged and as there is an increase in the pressure due to this accumulation, the fluid starts to leak from the wall. This will enter peritoneum and necrosis. This will result in an acute emergency when it becomes serious.
