Fill in the blank
The ___ bilayer structure of the cell membrane is made possible because___ molecules contain two distinct regions.
Lipid, phospholipid
Concerning the cell membrane
The____ region is attracted to water.
Hydrophilic
The _____ of the phospholipids thus create an internal and external membrane surface.
Polar heads
The ____ region is repelled by water,
Hydrophobic
So the _____ of the phospholipids create an internal layer that will not interact with water.
Non polar tails
What is a hypotonic solution?
A. A solution that has lower concentration of water than exists in the cell.
B. A solution that has a greater concentration of water than in the cell.
C. A solution that has a lower concentration of solute inside the cell.
D. A solution that has a greater concentration of solute outside the cell.
E. A solution that constantly varies in concentration when compared to what exists in the cell.
A.
Remember hypotonic the cell expands with water
Less salt more water than whats in the cell so it fills with water to equalize.
