What is the role of scientific research in solving human health problems

The function of scientific research in solving issues of human health differs on the basis of what field one is studying. As it can aim at the diagnosis, causes, or treatments of the condition.  

If one is looking at the causes, science will assist in focusing on what the issue actually is. At the same time, science can also assist to find the best treatments. Once one can find a cause, one can even figure out the best treatment for it.  

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
