Antidiuretic hormone (ADH) and the renin-angiotensin-aldosterone system (RAAS) work together in maintaining osmoregulatory homeo
julsineya [31]

Answer:

The correct answer will be- ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions.

Explanation:

To maintain the osmolarity of the blood in the human body, the body activates the RAAS pathway and the production of ADH.

RAAS pathway gets activated when the receptors sense low blood pressure in the body. This activates the production of renin from the juxtaglomerular cells of the body which converts the angiotensin to angiotensin I and later angiotensin II.

This allows the reabsorption of sodium ions in the blood through proximal and distal tubules in the nephron.  This activates the synthesis of aldosterone which increase the permeability to sodium ions.

The Antidiuretic hormone helps regulate the low blood pressure by adding aquaporins to the distal tubule membrane which help absorb the water.

Thus, ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions is the correct

there are multiple chickens and rabbits in a cage there are 72 heads and 200 feet inside of the cage how many chickens are in th
schepotkina [342]
The answer is 44 chickens and 28 rabbits.

We have a system of two equations.
x - the number of rabbits
y - the number of chickens

Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.

Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.

Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
