A) increases the permeability of the collecting ducts to water.

Explanation:

Antidiuretic hormone. Hormone released primarily in response to changes in serum osmolarity or blood volume. It causes the kidneys to conserve water by concentrating urine and reducing its volume, stimulating water reabsorption.

The antidiuretic hormone (ADH), or arginine vasopressin (AVP), is a hormone released primarily in response to changes in serum osmolarity or blood volume. Also known as argipressin. It causes the kidneys to conserve water by concentrating urine and reducing its volume, stimulating water reabsorption, increasing the permeability of the collecting tubules for water. It is named after this important function as a homeostatic fluid regulator. It also has functions in the brain and blood vessels. It is a small hormone (oligopeptide) consisting of nine amino acids: NH2-Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-COOH. Vasopressins are peptide hormones produced in the hypothalamus. Most are stored in the back of the pituitary gland (neurohypophysis) in order to be released into the bloodstream, some of them being released even directly in the brain. Vasopressin is in high concentrations in the locus coeruleus and in the black substance, which are catecholaminergic nuclei.

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

$p(t)=0.3t^2+6t+80$

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

$p(0)=0+0+80=80$

according to question, we have said that if the population has twice its initial population, then it becomes

$p(t)=2\times 80=160$

so, time taken to reach this above mentioned population is given by

$160=0.3t^2+6t+80\\\\160-80=0.3t^2+6t\\\\80=0.3t^2+6t\\\\0.3t^2+6t-80=0\\\\\text{using quadratic formula ,we get }\\\\t_{1,\: 2}=\frac{-60\pm \sqrt{60^2-4\cdot \: 3\cdot \: 800}}{2\cdot \: 3}\\\\t=-29.14\ and\ t=9.149$

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
