Please answer.
mars1129 [50]

Answer:

The correct answer is D. an unbalanced force.

Explanation:

If an unbalanced force were applied to the glass of water (for example, someone pushing the glass, lifting it up, etc.), this would cause it to move.  However, a balanced force (if two people were to simultaneously pull the glass in opposite directions with the same amount of force) would not cause the glass to move.  Gravitational force acts on all objects; the force due to gravity is already acting on the cup at rest and will not cause it to undergo motion.  Friction is also already acting on the cup in the form of static friction, making it harder for someone to move the cup, so frictional force will not cause the cup to move either.  Therefore, the correct answer is D. an unbalanced force.

Hope this helps!

Before the forming urine flows into the distal tubule of the nephron, it is in the _____ ______ _____, where water is absorbed a
liraira [26]

Answer:

<em>"Before the forming urine flows into the distal tubule of the nephron, it is in the </em><em>loop of Henle</em><em>, where water is absorbed as the fluid descends into the deep medulla of the kidney, and salts are absorbed as the fluid flows back up to the cortex of the kidney".</em>

Explanation:

Henle´s loop is a specific section of renal tubules that forms the nephrons.

In this U-shaped region, the two parts of the contorted tubule, the distal and the proximal part, are very close to each other. In the kidney, both parts of the tubules are located in the renal cortex, while the loop of Henle is located within the renal medulla.

The proximal region of the Henle´s loop is a permeable region, unlike the proximal and distal regions of the renal tubule.  

This is why it is possible the interchange of water and ions in the Henle´s loop. In the loop´s walls, cells present aquaporines in their membranes that allow passive water absorption, while they do not allow the transport of ions and urea. In this way 25% of the water that passes through the kidney might be filtered.  

The ascendant side of the loop, which is narrower, the tubule wall is impermeable to water but allows the ions´reabsorption. Here, cells present sodium, potassium, and chloride channels.

Potassium sodium pump transporters are found in the basolateral zone. While in the apical area are active transporters of the 3 ions.

Due to these differences in the water and ions´absorption between the two parts of the Henle´s loop, a countercurrent multiplier effect is produced, stratifying the osmotic compounds of the medullary interstitium, being the part closest to the cortex less concentrated than the part closest to the renal papilla, which is about 4 times more concentrated in ions.
