Explain the movement of solvents and solutes in these processes. What is isotonic dehydration? If an animal cell shrinks, it was probably placed in a: A.) hypotonic solution B.) hypertonic solution C.) isotonic solution If the environment outside a cell is hypertonic, how will the cell ...
7. The influence of [K] i on membrane potential was investigated by changes in tonicity of the external solution. Hypotonic solution produced a change in intracellular K activity close to that produced by ideal water movement. However,... HA Fozzard,CO Lee - 《Journal of Physiology》 被引量...
What keeps plant cells from bursting in a hypotonic solution? What protects the plant cell? What would enhance water uptake by a plant cell? What regulates the flow of water through the xylem? What structure in a plant cell prevents lysis?
Pressure from the process of osmosis -- the movement of water from the outside to the inside of the plant's cells -- keeps up the plant's cell walls. When you water a plant, it sucks up the water through capillary action. Then the water travels from the roots through tubes called xy...

What is the role of the blood in the regulation of pH of the body? What would the effect(s) of a tumor that secretes renin on plasma potassium levels? Discuss why water will always move from a hypotonic solution to a hypertonic one if the membrane is permeable to water. ...

Carrier-mediated water cotransport is currently a favored explanation for water movement against an osmotic gradient. The vestibule within the central pore of Na+-dependent cotransporters or GLUT2 provides the necessary precondition for an osmotic mechanism, explaining this phenomenon without carriers. Sim...
Tonicity is defined by cell behaviour in solution and the solution is either isotonic, hypotonic or hypertonic. PTC: The tonicity of a solution is dependent on the osmotic concentration and also the membrane behavior of the solutes. An isotonic solution will contain a minimum of 300 milliOsm/L...
Mouthparts, except the maxillary palps, and eyes were embedded in dental cement (Ketac™ Cem radiopaque, 3 M ESPE, Seefeld, Bayern, Germany) to prevent movement of the head. A 0.1 mm diam. tungsten recording electrode sharpened by electro polishing in saturated KNO2 solution was placed ...
