What is most likely to happen if you take a cell out of a solution with a low concentration of dissolved particles, and then place it into a solution with a high concentration of dissolved particles?
A.
There would be no change to the cell.
B.
There is not enough information given to determine what type of solution the cell is immersed in.
C.
Water would rush into the cell, causing the cell to swell.
D.
Water would rush out of the cell, causing the cell to shrink.
Which of the following statements best describes active transport?
A.
the movement of molecules across a cell membrane without the input of energy and without carrier molecules
B.
the movement of water across a cell membrane from an area of high concentration to an area of lower concentration
C.
the movement of molecules across a cell membrane with the input of energy from the cell
D.
the movement of molecules across a cell membrane by means of a carrier molecule without the input of energy
A cell containing a very low solute concentration is placed into a higher solute concentration. In what type of solution is this cell immersed?
A.
isotonic
B.
hypertonic
C.
hypotonic
