Answer:
WATER REABSORPTION IN THE COLLECTING TUBULE OF TE KIDNEY
Explanation:
Antidiuretic hormone synthesized by the neurons in the hypothalamus and the posterior pituitary allows for the reabsorption of water from the collecting ducts of the kidneys back into the circulation.
This therefore reduces the amount of water in the urine causing the formation of concentrated urine and reduced volume of urine.
It causes the increased reabsorption of sodium in the ascending loop of Henle adding to the counter-current mechanism which aids the further reabsorption of water from the distal tubules and collecting ducts.
It also allows the constriction of arteries thereby reducing arterial blood pressure.

Answer:
To increase the duration of effectiveness of local anesthesia.
Explanation:
Local anesthesia is best effective when its rapid absorption in systemic blood vessels is prevented. Diffusion of anesthesia along with blood reduces the period for which it is active. Epinephrine is a vasoconstrictor and does not allow the local anesthesia to diffuse rapidly. Concentrating the anesthesia locally increases the duration for which it is active.
A and C are balanced while B is unbalanced.
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
