Most health experts recommend eating tuna a few times a week and eating shark few times a month because: eating these fish could result in the buildup of pollutants in fat tissue of humans.
<h3>Why health experts recommend tuna and shark to be consumed less?</h3>
Large fish like sharks and tuna feed on smaller fish and can accumulate high levels of environmental pollutants like mercury and the risk also increases as off-shore pollution increases.
Shark meat is recommended only a few times a month because sharks are apex predators who accumulate high levels of toxic chemicals and heavy metals from both skin absorption and from consuming prey. This is called bioaccumulation.

Answer:
(A) - The volume of the blood plasma increases on overhydration and decreaes on dehydration.
(B) - Osmolality of blood increases with the dehydration and decreases with the overhydration.
Explanation:
If the levels of drinking water is increased, then the plasma becomes more dilute and the plasma volume increases because <u>the water will be reabsorbed more and which as a result reduces plasma concentration of the solutes and increases volume of plasma.</u>
Plasma osmolality measures electrolyte-water balance of the body. <u>As mentioned, above on overhydration, the plasma concentration of the solutes decraeses which also decreases osmolality. So, Osmolality of blood increases with the dehydration and decreases with the overhydration. </u>Increased osmolality in blood stimulate the secretion of antidiuretic hormone which results in the increased water reabsorption and therefore, more concentrated urine and hence blood plasma with less concentration.
