15. A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?
A. The swollen gums have absorbed the saltwater solution.
B. The saltwater solution lowers the temperature of the water in the gums.
C. The salt in the solution has moved against the concentration gradient.
D. The water in the gums has moved out due to the high concentration of salt in the solution.
"Channel proteins" in the membrane form tunnels through which molecules too large to move through the membrane can pass in and out of the cell. This is called______
Osmosis
Facilitated Diffusion
Simple Diffusion
Protein pumping
Osmosis is specifically.....
diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
the diffusion of particles from an area of high concentration to an area of low concentration
diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
the diffusion of particles from an area of low concentration to an area of high concentration
In the cell pictured, which way would water move?
Into the cell, causing the cell to swell
Out of the cell, causing the cell to shrink
In and out of the cell equally, keeping the shape the same
Osmosis is the diffusion of ____ across a selectively permeable membrane
food
air
water
oxygen

Cell membranes are described as selectively permeable.
Four students were asked to explain what this means. Which one is correct?
Student 1: Cell membranes prevent all materials from entering the cell.
Student 2: Cell membranes only provide structural support for the cell.
Student 3: Cell membranes regulate which substances can enter and exit the cell.
Student 4: Cell membranes allow water and water-soluble substances to enter the cell.
