Part C - Some microbes are halophiles and can withstand a high concentration of salt in their environment. What happens to nonhalophiles under such a condition?
| Salt enters the cell. |
| Water enters the cell. |
| Salt leaves the cell. |
| Water leaves the cell. |
Homework Answers
I believe the correct answer to be:
Option D) Water leaves the cell.
As the concentration of water is higher inside the cell than outside the cell due to which the water will move from higher concentration to lower concentration outside the cell.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

3. A 1000-gallon tank initially contains 800 gallons of water with 3 lbs of salt dissolved in it. A water-salt mixture with a concentration of 0.4 lb of salt per gallon enters the tank at a rate of 8 gal/hr. The liquid in the tank is well-mixed and is pumped out of the tank at a rate of 10 gal/hr. Suppose you were asked to find an expression for the amount of salt in the tank at time t. (a)...

In many biological solutions, water is the solvent, meaning that solute molecules are dissolved in it (think of salt or sugar water). If a solute does not move across a semipermeable membrane, it is асr known an osmotically active solute. For the following examples, assume that the solute is osmotically active. In osmosis, water molecules move across the cellular membrane down the gradient (from an area of low solute/high water concentration to an...
