Positive
A cell that is more positive and less negative is depolarized.
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.
The correct answer is D. Hypertension.
Explanation
Arterial hypertension is a disease of the circulatory system of the human body in which the pressure of blood flow through the veins and arteries increases above normal levels increasing the risk of cardiovascular accidents, coronary heart disease, heart failure, cerebrovascular accidents, and renal insufficiency.
A third of the world's population suffers from this condition and it is the first cause of visiting the doctor. Also, this disease is related to certain habits including, eating habits, sports activities, and the consumption of substances such as cigarettes and alcohol. So, the correct answer is D.
