Answer;
can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes
The skin is permeable to organic solvents, such as acetone or turpentine, because they can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes.
Explanation;
-Human skin has a low permeability; that is, most foreign substances are unable to penetrate and diffuse through the skin. Skin's outermost layer, the stratum corneum, is an effective barrier to most inorganic nanosized particles
Metals are known to be excellent conductors of electricity, however some metals do not conduct electricity as well as gold, copper or sliver (examples of good conductors). Metals such as lead, mercury and alloys of iron, chromium, titanium and stainless steel do not conduct electricity as good as silver, copper and gold. It is also important to note that all gases do not conduct electricity at all due to the great amount of space between its electrons.
