Question

question 12 (1 point) if a cell is placed in a hypotonic solution, there will be a net movement of water out of the cell. water will never move. water will move equally in and out of the cell. there will be a net movement of water into the cell. question 13 (1 point) when red blood cells are placed in a hypertonic solution water will: move into the cells causing hemolysis. move out of the cells causing hemolysis. move out of the cells causing crenation. move into the cells causing crenation.

Explanation:

In a hypotonic solution, the solute concentration outside the cell is lower than inside, so water moves into the cell by osmosis. In a hypertonic solution, the solute concentration outside the cell is higher than inside, so water moves out of the cell, and for red - blood cells, this causes crenation (shrinking and wrinkling of the cell).

Answer:

Question 12: there will be a net movement of water into the cell.
Question 13: move out of the cells causing crenation.
