Answer:
An aqueous stagnant layer that overlies the apical membrane and the subepithelial blood flow are potential barriers to the absorption of drugs that readily penetrate the absorbing cell of the epithelium. The apical, basal, and basement membranes are potential barriers to the absorption of less permeable drugs.
I think its Mercury because it's the closest to the sun.

Answer:
Answer is 5.76×10^-25.
Explanation:
Given values in the question are:
q = 1.6 x 10⁻¹⁹ C
k = 9 x 10⁹ N.m²/C²
Hence two points is 20mm apart so the radius becomes
R=0.02.
The formula is
F = kq^2/r^2
F= 9 x 10⁹× (1.6 x 10⁻¹⁹)^2 /(0.02)^2
F=5.76×10^-25.
