Only the lipid soluble non-ionized form of a drug can diffuse across the membrane. The pH is low in the stomach. For the acidic drugs, they are non-ionized at low pH yet they are poorly soluble. For the basic drugs, they are soluble yet ionized.
The primary site of nutrient digestion is the small intestine, but this also takes place to a lesser extent in the stomach and mouth. The small intestine is also where the majority of digested nutrients are absorbed.

lungs and to a significant extent their skin.
Probability is the likelihood of something happening. It is the extent to which something is likely or unlikely to occur.
To the extent to which the energy is absorbed, yes. Reflectivity and color determine how much energy is absorbed, but no matter can reflect 100% of the energy striking it. Some will be absorbed by the molecules.
No. stomach does not store the food. It digest the proteins to some extent.
