Help me with this? It's only 15 points
Natalka [10]
I believe the answer is “false”. While it’s true that many sea anemone will stay in one spot that they are happy with, it’s not true for all. Many sea anemone move around, especially when they are younger. It’s when they’re older they are more sessile.

Why is it important that saline solution has a specific concentration when a person is put on an IV drip of saline?
timurjin [86]

Answer:

Doctors utilize IV saline for refilling lost fluids, flushing wounds, providing medication, and maintaining patients through surgery, dialysis, and chemical treatment. As a fashionable therapy, Saline IVs even found a space outside the hospital.

"There are significant quantities of sodium and chloride, higher than blood levels.

Explanation:

The solution of sodium chloride-water, generally known as saline, is the saline solution. It is the intravenous fluid most usually used. It was utilized since the early decades of the 19th century and is used annually in the United States alone with more than 200 million liters.

Though about 60 percent of the body consists of water, it is not possible to inject water into the blood alone, because the blood could lead to the depletion of important electrolytes.

Direct water injection into the bloodstream would likewise lead to the blood cells' osmotic impact.

Blood cells, which are predominantly salty, will take water and cause it to expand quickly until the cell membrane breaks down. The content of the cells would then leak into the plasma. A substantial proportion of body cells can be damaged to death. Death can result.

There would be no permanent harm to a little amount of water injected into the blood directly. The bigger the number of cells injured, in essence, the more water injects into the circulation.

Water is blended in a solution in sodium and chlorine at approximately the same concentration as blood plasma to avoid damages caused by pure distilled water on blood cells. The outcome is that the solution splits the circulating volume with the cellular fluid and becomes an integral part of the circulating volume without a detrimental influence on blood cells.
