<u>Answer</u>: Birds

<u>Explanation</u>:

1. Archaeopteryx is considered  as an intermediate between birds and reptiles.

2. The characters similar to birds was the presence of  feathers along its arms and tail.

3. However, the shoulder girdles, pelvis, and feet were not fused and reduced as seen in case of living birds.

4. Further, they also had teeth and bony tail.

Thus, <em>being a bridge between birds and reptiles they led to the evolution of birds.  </em>

adh or vasopressin... group of answer choices all of these options are correct promotes the insertion of aquaporins (specificall
vagabundo [1.1K]

Two of these options are correct (A & E)

So, the correct option is D.

<h3>About ADH/Vasopressin:</h3>
  • Other name for ADH is arginine vasopressin.
  • It is a hormone produced by the brain's hypothalamus and kept in the posterior pituitary gland.
  • It instructs the kidneys on how much water to hold onto.
  • The amount of water in your blood is continuously regulated and balanced by ADH.
  • Your blood's volume and pressure increase with higher water concentration.
  • ADH helps to sustain water metabolism along with osmotic sensors and baroreceptors.
  • The concentration of particles in your blood causes osmotic sensors in the hypothalamus to respond.
  • Carbon dioxide, sodium, potassium, chloride, and other chemicals are among these particles.
  • These sensors and baroreceptors tell your kidneys to store or release water to maintain a healthy range of these substances when particle concentration is out of balance or blood pressure is too low.
  • They also control how thirsty your body feels.
  • The particular nerve cells that make anti-diuretic hormone are located in the hypothalamus, a region at the base of the brain.
  • The hormone is sent by the nerve cells to the posterior pituitary gland, where it is released into the bloodstream, via their nerve fibers (axons).
  • By influencing the kidneys and blood arteries, anti-diuretic hormone aids in maintaining blood pressure.
  • Its primary function is to decrease the volume of water excreted in the urine, so conserving your body's fluid volume.
  • This is achieved by permitting a specific region of the kidney to enable water from the urine to be reabsorbed into the body.
  • As a result, the bloodstream is replenished with more water, urine concentration increases, and water loss is decreased.

<h3> Aquaporins and ADH:</h3>
  • Antidiuretic hormone levels above a certain threshold narrow (constrict) blood arteries, raising blood pressure.
  • The only way to fully recover from a lack of bodily fluid (dehydration) is by drinking more water.
  • The aquaporin 2 protein is made according to instructions from the AQP2 gene.
  • The water molecules are transported across cell membranes by this protein, which creates a channel.
  • Collecting ducts, a network of tiny tubes that reabsorb water from the kidneys into the bloodstream, are found in the kidneys where it is discovered.
  • In order to keep the body's water balance in check, the aquaporin 2 water channel is crucial.
  • A hormone known as vasopressin or antidiuretic hormone regulates the positioning of these channels (ADH).
  • The body creates more ADH when the amount of fluid consumed is low or when there is a lot of fluid loss (for instance, through sweating).
  • Aquaporin 2 water channels are ultimately inserted into the membrane of collecting duct cells by this hormone, which sets off chemical events.
  • Due to the re-absorption of water into the bloodstream made possible by these channels, the urine is more concentrated.
  • Less ADH is created when fluid intake is sufficient. Aquaporin 2 water channels are taken out of the collecting duct cells' membrane in the absence of signals from ADH.
  • During these times, the urine is more diluted and less water is reabsorbed into the bloodstream.

Disclaimer: The given question was incomplete on the portal. Here is the complete question.

Question: ADH or Vasopressin...

A. Promotes the insertion of aquaporins (specifically AQP2) into the apical membrane of the collecting duct cells

B. Promotes the insertion of aquaporins (specifically AQP3 and AQP4) into the basolateral membrane of the collecting duct cells

C. All of these options are correct

D. Two of these options are correct

E. When released, increases the osmolarity of the excreted urine

Every year a rice farmer collects his crops and burns the soil when he is done once the soil is enriched with debris he replants
brilliants [131]

Every year the farmer was taking care of his ice field, keep it clean and clear of all the unnecessary shrubs and then reuse the debris to fertile the soil again and then grow rice again. But since he fell sick, there is no one to take care of his rice field which will leads to the growth of unnecessary plants and weeds in it.

There will grow wild plants and shrubs which will contaminate the rice field.
