Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%

Answer:
The correct answer is option C-ANP (Atrial natriuretic peptide).
Explanation:
Vasoconstriction is the narrowing of the blood vessels which can stop or block the blood flow.
Vasoconstriction reduces the urine formation during stress conditions through the action of hormones like ADH (anti-diuretic hormone), norepinephrine, epinephrine and angiotensin II produced via the sympathetic nervous system.
The atrial natriuretic hormone (ANP) is a cardiac hormone produced to lower the blood pressure or reduce blood plasma through vasodilation, increased vascular permeability and increase renal excretion.
Thus, option C is the correct answer.
