Suppose you are examining osmosis by studying a carrot soaking in water. First, you conclude that the cell walls of the carrot are semipermeable, allowing water molecules but not solutes to passively move into and out of the cell. Next, you measure the solute concentrations of the carrot cells and the surrounding water. You determine the carrot cells contain a higher solute concentration than the water in which the carrot is soaking. Which statement accurately describes this scenario? Group of answer choices The cells of the carrot are hyperosmotic compared to the surrounding water, so water will be drawn out of the cells through osmosis The cells of the carrot are hypoosmotic compared to the surrounding water, so water will be drawn out of the cells through osmosis The cells of the carrot are hypoosmotic compared to the surrounding water, so water will be drawn into the cells through osmosis The cells of the carrot are hyperosmotic compared to the surrounding water, so water will be drawn into the cells through osmosis

1) We measured weights before and after soaking a potato in water of different salinities to demonstrate osmosis. There are many other types of membrane transport (as we learned from the Amoeba Sisters!), each with their role in maintaining homeostasis and providing energy, communication, and waste removal for the cell. So why dwell on osmosis? There are some practical bigger- picture things to consider. Choose one of the following scenarios. Describe the scenario. Describe the chain of events terms of tonicity_and movement of water into or out of cells represented by the scenario. Describe the predicted outcomes for the cells/organisms involved. What happens when you dry brine a turkey before cooking? ● • What happens to organisms in soil near salted roads when snow melt and rains occur? Why is sugar considered a good preservative? What is the challenge of heavy rains along the Mississippi River for organisms in the Gulf of Mexico? ● • What happens to fruit when you add sugar? ●
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.
Americans spend up to $100 billion annually for bottled water (41 billion gallons). The only beverages with higher sales are carbonated soft drinks. Recent news stories have highlighted the fact that most bottled water comes from municipal water supplies (the same source as your tap water), although it may undergo an extra purification step called reverse osmosis.Imagine two tanks that are separated by a membrane that's permeable to water, but not to the dissolved minerals present in the water. Tank A contains tap water and Tank B contains the purified water. Under normal conditions, the purified water would cross the membrane to dilute the more concentrated tap water solution. In the reverse osmosis process, pressure is applied to the tap water tank to force the water molecules across the membrane into the pure water tank.If you shut the system off and pressure was no longer applied to Tank A, you would expect (a) the water movement to follow the concentration gradient. (b) the water…

A concentration gradient for water must be present in cells for osmosis to occur. Which bag represented the steepest concentration gradient relative to its surrounding environment?
Students set up an experiment in which they filled dialysis tubing with a 3% starch solution. They tied off the ends of the tubing and placed it in a beaker filled with distilled water and 1% iodine for 3 hours as shown in the diagram. 3% starch solution 1% lodine solution Since dialysis tubing is semi-permeable like the plasma membrane, the bag of white starch solution was bluish- black the next day. What is the best explanation for the results? (1D) O The starch solution diffused into the beaker because the concentration of water is greater in the starch solution than in the iodine solution. The iodine solution diffused into the bag because the concentration of water is greater in the starch solution than in the iodine solution. O The lodine solution diffused into the bag because the concentration of water is greater in the iodine solution than in the starch solution. O The starch solution diffused into the beaker because the concentration of water is greater in the iodine solution…

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. (c) Describe the environmental conditions taking place in each of the six solutions with the apples refer to picture for table
The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.

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?
