Questions and Answers
A cell with an internal salt concentration of 0.8% is placed in a solution with a salt concentration of 1.2%. Which of the following describes the movement of water across the cell membrane?
A cell with an internal salt concentration of 0.8% is placed in a solution with a salt concentration of 1.2%. Which of the following describes the movement of water across the cell membrane?
- There is no net movement of water.
- Water moves out of the cell. (correct)
- Water moves into the cell.
- Salt moves out of the cell, balancing the concentration.
In a hypotonic solution, a cell will typically shrink due to the net movement of water out of the cell.
In a hypotonic solution, a cell will typically shrink due to the net movement of water out of the cell.
False (B)
Describe how a semi-permeable membrane contributes to maintaining cell homeostasis.
Describe how a semi-permeable membrane contributes to maintaining cell homeostasis.
A semi-permeable membrane allows selective passage of molecules, maintaining internal balance by controlling the influx of nutrients and efflux of waste products.
If a cell is placed in a(n) ______ solution, water will move into the cell.
If a cell is placed in a(n) ______ solution, water will move into the cell.
