QUESTION 24.
Answer- A. cell will shrink
Hyper means "more", hypertonic cell means more concentrated solution. In other words, a hypertonic solution is having more solute concentration than cell, so solvent more from a region of high concentration( from inside of the cell) to low concentration (outside of the cell).
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!

3. You make a solution that contains 1000 molecules of water. 90 molecules of glucose, and 120 molecules of sucrose. What is the solute concentration of this solution? (2 points) 17.35/ 4. You now add a cell into the solution from question 3. This cell has a 20% solute concentration. a. Is the outside of the cell hypertonic, hypotonic, or isotonic when compared to the inside of the cell? How do you know?...

Question 2 1 pts Consider a cell immersed in a solution. Which of the following statements is not true? When a cell is immersed in a hypertonic solution, there is a net flow of the solvent out of the cell. When a cellis immersed in a hypertonic solution, the concentration of the solute inside the cell is smaller than the concentration of the solute in the solution. When a cell is immersed in a hypotonic solution, the concentration of the...
