Cell Membrane Function
The relative concentration of water in a hypotonic solution is:
high
The maintenance of a constant internal body environment
homeostasis
greater than, high
hyper
A higher salt concentration than inside the cell
hypertonic
The diffusion of water across a semipermeable membrane
osmosis
less than, low
hypo
A lower salt concentration than inside the cell
hypotonic
allows all substances to pass through:
permeable membrane
stable
stasis
An example of homeostasis in the human body is the glucose, pH, CO2 concentration in the blood being kept constant.
true
If you have two solutions separated by a semipermeable membrane, one having a 7 % concentration of salt in water and the other having a 12 % solution of salt in water, the water will flow from the side with the % solution to the side with the % salt solution.
7%, 12%
Homeostasis is the maintenance of a internal environment by the body.
constant
The relative concentration of water in an isotonic solution is:
equal
cell shrinks:
hypertonic solution
higher salt concentration than inside the cell:
hypertonic solution
Which way will water flow for the following external solutions?
hypertonic: out of the cell hypotonic: into the cell
cell bursts:
hypotonic solution
lower salt concentration than inside the cell:
hypotonic solution
same
iso
The same salt concentration as inside the cell
isotonic
cell stays the same:
isotonic solution
same salt concentration as inside the cell:
isotonic solution
The relative concentration of water in a hypertonic solution is:
low
Not having a charge or partial charge
nonpolar
The passage of water through a semipermeable membrane is called
osmosis
Any molecule can pass through without hindrance
permeable membrane
A membrane which limits the type of molecules which will pass through it is called
semipermeable
Allows some molecules to pass through but excludes others
semipermeable membrane
allows some substances to pass through; excludes others:
semipermeable membrane
If you were stranded on the ocean in a raft, what would happen if you kept drinking ocean water?
your blood would become hypertonic the concentration of water in your blood would decrease water would flow out of your body cells
