- B) Rate of transport into the cll A or B 10 20 30 40 Time (min) The graph directly above shows the rate of substance transport over time when the cells that do not contain the compounds A, B, or C, are placed in 1 mM solutions of A, B, and C, respectively. Based upon these data which of the following is/are compatible modes of transport for substance A? (active transport, facilitated diffusion, simple diffusion) For substance B? For substance C?After sweating through a long marathon, a runner decides to replenish their body fluids by drinking an amount of pure water that is equal to the volume of lost bodily fluids. Which of the following describes the most likely impact on the cells in the body of the run- ner as a result of this action? A B с D The cells will swell because they will become hypertonic relative to their normal solute concentration. The cells will shrivel up because they will become hypotonic relative to their normal solute concentration. The cells will swell because they will become hypotonic relative to their normal solute concentration. The cells will shrivel up because they will become hypertonic relative to their normal solute concentration.DO NOT COPY THE ANSWER FROM THE SAME QUESTION. Sassa, a biology professor, wanted to demonstrate to her students the applicability of a dialyzing membrane (DM) as a model for the cell membrane by enclosing an aqueous solution in a DM bag and immersing in a beaker containing a different solution. Substances available which are permeable to the DM include 0.02 M NaCl, 0.03 M glucose, and 0.01 M glucose. The only substance available which is completely impermeable to the DM is the 0.01 M lactose. Using the substances given and materials such as a beaker, stirring rod, and string, draw ONLY ONE set-up that can be demonstrated by Ms. Sassa that will satisfy ALL of the following conditions:a. No solute will exhibit a net diffusion out of the cell.b. Glucose will exhibit a net diffusion into the cell.c. NaCl will exhibit a zero net d. No net movement of lactose from the inside to outside of the cell. Make sure to label properly the substance inside the beaker and inside the DM bag.
- Diffusion and osmosis classification Classify the following characteristics based on whether they are describing diffusion, osmosis, or both. Diffusion Results in an Can occur with equal distribution of solute molecules or without a membrane Always involves the movement of water Requires a semi-permeable membrane Osmosis Involves the movement of gases, ions, and small water soluble molecules Passive form of movement that requires no energy Moves from areas of high concentration to low Both Diffusion and Osmosis Responsible for gas exchange in the lungs concentration A 3 of 15 Next > Cation to open the document "Epicinstaller-13.0.0-fortnite-a8e4f12cada646caa706d8be407be69f (3).msi". tv 22TONICITY DRAGTHE WORDS INTO THE BLANK SPACES BELOW TO ACCURATELY COMPLETE THE PARAGRAPH decreases Hypertonic increases key: Hypotonic solute particle • cell membrane cell wall solute in all solutions, the solvent is H20 solvent A В Solution B is to solution A. This is because solution B has a greater concentration of in it than does solution A. Solution C has no solutes dissolved in it, therefore it is to both Solutions A and B. As the relative concentration of solutes in two solutions increases, of necessity the relative concentration of water in the same two solutions Solution A has a lower concentration of than does Solution C; Solution A is also hypertonic to Sol tion C.The intracellular salt content of a red blood cell is about 150 mM. The cell is put in a 500 mM salt beaker. (a) Describe what will happen to the cell in terms of osmosis if the cell membrane is permeable to water but not to ions. (b) Which direction would solutes diff use if the membrane was permeable to ions: into or out of the cell?
- In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution. (b) Identify the osmolarity of the apple.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)? NDiffusion and Osmosis What is your prediction about the effect of molecular weight on rate of diffusion? What is your prediction about the effect of temperature on rate of diffusion?
- The average concentration of salt in seawater is about 3.5 percent and the average concen- tration of salt in the human cellular environment is about 0.9 percent. Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.In the experiment showing osmosis through a semipermeable membrane, 3 corn syrup mixtures are used. If equal volumes of two solutions (10% corn syrup and 30% corn syrup) were placed in two beakers that were separated by a semipermeable membrane, permeable only to water, and let sit for 1 hour, what would be the expected concentration/s of the two solutions at the end of the time period? Explain using solute concentration, water concentration etc.Piston C Piston D Solution A Solution B Semipermeable membrane Above is a crude cartoon of a diffusion system. Two containers with solutions of sucrose in water are connected by a semipermeable membrane that is only permeable to water. Each container has a piston above it. Using this information answer the following. If the concentration of sucrose in solution A is 150mM and in solution B it's 2mM, which of the following would occur? al Piston D will feel an upward pressure. No diffusion will occur. Sucrose will diffuse from solution A to soluion B. Piston C will feel an upward pressure.
