Gorter and grendel extracted lipids from human red blood cells. they calculated the total surface area for these red blood cells
Anastaziya [24]
<span>The calculated to surface area for red blood cells by Gorter and Grendel found to be 36u2.

 The surface area that would be covered once they spread across the surface of the water is 72u2.

If they spread across the surface area will double. This is because the lipid bilayer with phospholipid the head faces the water on each surface of the membrane.
 It clearly shows that there must be more to membranes than lipid bilayer because membranes grew and the surface tension of membranes is much lower than those of pure lipid structures.</span>

List the 3 types of cell junctions and state which is the most and least permeable.
Zanzabum
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly.  I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.

What five factors affect photosynthesis and it's rate?
mixer [17]
There are more than 5 factors, but here are perhaps the most important ones:
1) Light: Light energy is a crucial component in photosynthesis, as it is the primary energy source of the process.
2) Carbon Dioxide: Another key ingredient in photosynthesis.
3) Temperature: There is an optimum temperature for photosynthesis that varies from organism to organism. Too cold or two hot, and rate of photosynthesis will be lower. 
4) Water - Like almost all life process, water is a key component in photosynthesis. 
5) Oxygen. A common misconception is that plants only "breathe in" carbon dioxide and expel oxygen. Plant cells actually require oxygen as well in order to function, and thus oxygen is a necessary part of photosynthesis.
