The hormone ADH functions to promote water re-abdsorption through the wall of what in the kidney?
ADH promotes water reabsorption through the wall of the collecting duct in the kidney by increasing the permeability of the duct to water. This helps regulate water balance in the body by allowing the reabsorption of water into the bloodstream.
What regulates water reabsorption in the distal convoluted tubules?
The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.
Is it possible for the kidney to increase water reabsorption without increasing salt absorption Explain?
Yes, it is possible for the kidney to increase water reabsorption without increasing salt absorption. This can occur through the action of antidiuretic hormone (ADH), which promotes the reabsorption of water in the collecting ducts without directly affecting sodium reabsorption. In conditions such as hyperosmolarity, the kidneys can concentrate urine by reabsorbing more water, while sodium levels in the body remain stable. Thus, water reabsorption can be enhanced independently of sodium absorption.
What happens when increasing the permeability of the membrane to K plus?
Increasing the permeability of the membrane to K+ will lead to more K+ ions moving into the cell, causing the cell to become more positively charged. This can impact the resting membrane potential and potentially lead to changes in cellular function and excitability.
What part of a plant collect water minerals?
Roots collect water and minerals from the soil, and additionally anchor the plant.

Does using fertilizer increase soil absorption?
It will limit soil absorption more than increasing it.
Why does cholesterol lower membrane permeability?
It sticks to the phosphate heads, preventing motion and increasing hydrophobic reactions.
What hormone is responsible for faculative water reabsorption?
Antidiuretic hormone (ADH), also known as vasopressin, is responsible for facultative water reabsorption in the kidneys. Its release is controlled by the body's hydration levels to regulate water balance by increasing the permeability of the collecting ducts in the kidneys.

The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.
What has tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area?
Villi are tiny fingerlike projects that increase a cells absorption capabilities by increasing its surface area.

Does increasing membrane permeability affect the time it takes for the osmometer to reach equilibrium?
Yes, increasing membrane permeability can affect the time it takes for the osmometer to reach equilibrium. Higher permeability allows for faster movement of solvent and solutes across the membrane, which can result in a quicker establishment of equilibrium between the two solutions.
How does the membrane potential affect the permeability of a neurons cell membrane?
The membrane potential influences the permeability of a neuron's cell membrane by affecting the opening and closing of ion channels. When the membrane potential changes, such as during depolarization, voltage-gated ion channels open, allowing ions like sodium (Na+) to flow into the cell, increasing permeability. Conversely, during hyperpolarization, channels may close, reducing permeability to certain ions. This dynamic alteration of permeability is crucial for generating action potentials and transmitting signals in the nervous system.
What is the meaning of vasopressin?
vasopressin is an antidiuretic hormone responsible for increased permeability of the distal tubules of the kidney, increasing water reabsorption and reducing urine volume.
