There are choices for this question namely:
<span>A. triglycerides
B. glucose
C. LDL
D. HDL
The correct answer is "LDL" or low density lipoproteins. Low density lipoproteins, also known as "bad cholesterol" are the one responsible for the deposition of fat and cholesterol onto the peripheral blood vessels, including the coronary arteries which poses a risk for developing atherosclerosis and its complications (i.e. ischemic heart disease). Niacin functions to overall improve the lipid profile of a patient by lowering LDL and raising the levels of high density lipoprotein or HDL also known as "good cholesterol".</span>
Osmosis is the process where there is some balancing of concentrations with the solvent moving. In this case, we have that within the fish and the water, the salt content is different; this creates a flow of water. IN THE SEA, the seawater has more salt and this creates a flow towards the sea from the cells of the fish; choice a WOULD BE correct in this case.
In freshwater though, we have that the fish has more salt inside it (higher concentration) than the surrounding water. Hence, water goes in the fish and the fish needs to conserve its salts in the form of urea; thus, they must consume lots of salt and have low urine. THE CORRECT ANSWER THUS IS B.
P.S. comment on osmoregulation: it does not happen when fishes are isotonic to their environment, namely they have the concentration of the water surrounding them; then no flow is created.
