Answer:
The correct answer is: 2) According to the given data, the surface area of all erythrocytes is (4.74x10^9)/(100x10^8)m^2. This is almost half of the surface area formed by a monolayer as Gorter and Grendel estimated it, leading to the conclusion that the surface of each cell was covered with two layers of lipids.
Explanation:
Each erythrocyte has a surface of 100 μm^2, which is equal to 100x10^-8 m^2. And to calculate the total area of erythrocyte counted, you should multiply the number of cells with the surface of one cell. This is (4.74x10^9)*(100x10^-8), which is equal to (4.74x10^9)/(100x10^8)=0.47m^2. This is approximately half of the surface area formed by the monolayer that was estimated. This is evidence that allows to conclude that the erythrocyte membrane is a bilayer
