Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
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.
