What happens to a red blood cell in a hypertonic, isotinic and hypotonic solution? How is the absorbance changing?

How is the rate of diffusion affected by an increasedconcentration gradient? By increased temperature of asolution? By increased viscosity of the solvent?

Soft contact lenses are made from hydrogels, which make them soft and flexible. It is important to clean them daily using a sterile, isotonic cleaning solution. The concentration of solutes in the cleaning solution is the same as the concentration of the hydrogel in the contact lens. What would happen if instead of an isotonic cleaning solution, soft contact lenses are cleaned with water? (A) The soft contact lenses will shrink because it will remove too much water by osmosis. B The soft contact lenses will shrink because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is absorbed by osmosis. The soft contact lenses will swell and change shape because too much water is removed by osmosis.

A red blood cell with an intracellular fluid (ICF) concentration of 280 mmol/L, is placed into an environment were the concentration of the extracellular fluid (ECF) is 305 mmol/L. As a result, water will move across the cell/plasma membrane. a) Name the process by which water moves b) Describe the overall direction of movement of the water. Answer choices: (i) From outside the cell to inside the cell (ii) From inside the cell to outside the cell, or (iii) Equally, into and out of the cell iii Explain your reasoning for your answer to part (c). 1In your answer you must describe the environment on both sides of the membrane, and use 3 of the following 4 terms correctly; hypertonic, hypotonic, lower solute concentration, higher solute concentrationn (2pts -Correct use of biological terminology, and correct spelling is essential.

A 150mM NaCl solution is isotonic to the red blood cells, causing no net movement of water into or out of the cells. Predict what would happen to the red blood cells in the following environments:   100 mM NaCl 300 mM NaCl 50 mM NaCl 0 mM (distilled water)

Blood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?

How do isotonic, hypertonic, and hypotonic solutions differ?

Red blood cells with an internal osmolarity of 300 mOsM/L are placed in a solution containing 300mOsm/L glucose. Which of the following must be TRUE about the solution? a) the solution is isosmotic b) the solution is isotonic c) both A and B d) Neither A nor B

What is one way in which the composition of intracellular and extracellular fluids differ?

The tonicity of blood plasma is 0.9% NaCl (equivalent to 99.1% water and 0.9% solutes.) What is the tonicity (express as a %) of red blood cells suspended in that plasma? How would you describe this tonicity (hypertonic, isotonic or hypotonic)? N
