biosis.



B)
endocytosis.

mitosis.



D)
osmosis.

7)
A cell with 1% solute concentration is placed in a beaker with a 5% solute concentration.

What will happen to this cell over time?

A)
The cell will gain H2O and expand.



B)
The cell will lose H2O and shrink.



C)
The cell will undergo no exchange of H2O with its surroundings.



D)
The cell will both gain and lose equal amounts of H2O ; thus, it will remain the same size.

B)
gain of water through osmosis



C)
loss of water through active transport



D)
gain of water through active transport

9. The cell is taking in substances through membrane proteins, without any energy expenditure of its own. The substances naturally follow their concentration gradient. However, they must go through the protein channels, because they are too large to squeeze through the cell membrane. This process is called

osmosis.



B)
endocytosis.



C)
active transport.



D)
facilitated diffusion.





10)
Which process describes the ATP-requiring movement of extremely large substances out of a cell in pockets called vesicles?
A)
exocytosis



B)
endocytosis



C)
phagocytosis



D)
passive transport





11)
Homeostasis will be MOST affected by the removal of the
A)
vacuole.



B)
cell wall.



C)
chloroplast.



D)
cell membrane.
