I have been given 3 questions to answer but i'm not sure how to answer them.
1. Describe how you would expect the phospholipid molecules to be arranged on the surface of the water?
2. Explain why you might expect the phospholipid molecules to cover an area approximately twice that of the total surface area
3. Explain how the reliability of the results can be assessed when investigating the effect of temperature or alcohol on the permeability of a cell membrane
Ooops forgot to add the starter so i'll write it again
In an experiment to investigate the structure of cell membranes; the phospholipid molecules from the surface membrane of a known number of red blood cells were carefully floated on the surface of water.
