Answer:
The preferable option will be - B.
B. juxtaglomerular complex.
Explanation:
The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus.
</u>
The given options were -
a. nephron loop (loop of Henle).
b. juxtaglomerular complex.
c. renal corpuscle.
d. filtration membrane.
e. afferent arteriole.
- The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
Your answer is actually all correct. Great job! A heterozygous combination would just implicate greater power to the 'dominant' dominant allele.
The circulatory system - hemoglobin in the blood transports oxygen :)
