the nuclear membrane
9
<p>What will happen: a cell with 20% salt solution placed in beaker with 40% salt solution</p>
<p>The cell will remain the same</p>
<p>the beaker will become hypertonic</p>
<p>the cell will become hypotonic</p>
<p>the cell will become hypertonic</p>
10
What kind of transport doesn't require the use of energy to move materials across the membrane?
diffusion
all of these don't require the cell to use energy
facilitated diffusion
osmosis
11
Movement of particles from an area of high concentration to an area of lower concentration is:
endocytosis
equilibrium
diffusion
osmosis
12
<p>What will happen: a cell with 20% salt solution placed in beaker with 40% salt solution</p>
<p>the water will come out of the cell</p>
<p>the salt will move into the cell</p>
<p>the water will move into the cell</p>
<p>there will be equal movement of water</p>
13
<p>what will happen: cell with 20% salt solution placed in a beaker with 40% salt solution</p>
<p>the cell will shrink</p>
<p>the cell will burst</p>

<p>active transport</p>
<p>diffusion</p>
23
Equilibrium is reached
at the end of active transport.
when movement of particles stops.
when particles are evenly distributed through the space.
only during passive transport.
24
Active transport
all of the answers are correct
moves materials against a concentration gradient
requires energy
is usually done by transport proteins in the cell membrane
