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:
Prostate fluid
Explanation:
Prostate fluid comes from the Prostate gland.
It propels seminal fluid into the urethra.
Answer: d. autonomic nervous system
Explanation:
The dilation of the pupil occurs due to the radial muscles. This is controlled by the autonomic nervous system. The autonomic nervous system consists of sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the dilation of pupil whereas the parasympathetic nervous system controls the contraction of pupil.
A dilation response generally involves the widening of the pupil that may be caused by the adrenaline and drugs like cocaine, MDMA, amphetamines, hallucinogens and dissociatives.
