Explain the mechanism maintaining osmotic gradient in renal medullary intestitium​

Biology

In the inner medullary collecting ducts it increases both water and urea permeability, which allows urea to flow passively down its concentration gradient into the interstitial fluid. This adds to the osmotic gradient and helps drive water reabsorption.

<em>In the inner medulla, urea recirculates, creating a greater osmotic gradient. It follows the concentration gradient formed by ADH-sensitive water reabsorption into the interstitial space from the collecting duct. The remaining water is drawn from the descending structures by increased interstitial osmolarity. </em>

<em></em>

<em>To maintain the vertical osmotic gradient, the blood supply to the renal medulla serves as a countercurrent exchanger. - The medullary vertical osmotic gradient is maintained by the vasa recta.</em>

<em>It enhances both water and urea permeability in the inner medullary collecting ducts, allowing urea to diffuse passively down its concentration gradient into the interstitial fluid. This contributes to the osmotic gradient and aids water absorption.</em>

TRUE OR FALSE : Cohesion is when water molecules stick to OTHER substances.
tekilochka [14]

Answer:

true

Explanation:

Thus when the positive side on one water molecule comes near the negative side of another water molecule, they attract each other and form a bond. This "bipolar" nature of water molecules gives water its cohesive nature, and thus, its stickiness and culpability

Typical rates of sea-floor spreading are appoximately
shutvik [7]
<h2>Answer:</h2>

<u>Typical rates of sea-floor spreading are approximately </u><u>5 cm per year</u>

<h2>Explanation:</h2>

Sea-floor spreading is a process that happens at the mid-oceanic ridge where a divergent boundary is causing two plates moving away from one another resulting in spreading of the sea floor. To calculate the spreading rate of one side of a mid-ocean ridge by dividing distance by time (Distance/Time = Rate) The typical rates of sea -floor spreading are approximately is 5 centimeter per year.

Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply.
zavuch27 [327]

If the water molecule was linear instead of bent, water would no longer produce hydrogen bonds. It will lose its polar properties and nearly all of its properties will change such as boiling point, water tension and solubility. It would be closer to gas, rather than liquid.

7. What do fruits do for the seed? *
Nikolay [14]
The function of a fruit with seeds is seed dispersal. There's no way a fruit could disperse seeds, if it didn't actually have a seed or seeds at some point. Fruits develop from the ripened ovaries of plants, once the ovule (egg) or ovules inside the ovary has been fertilized.
