Answer:
c.) The mucosa consists of a particularly vascular epithelium that facilitates efficient repair and renewal
a.) The tissue lining the stomach is an epithelium and thus capable of repair and renewal
Explanation:
The cells that form the lining of the stomach are deemed to wear out regularly due to the regular food intake they handle.
Due to this constant wearing, this cells have a mechanism of rejuvinating in order to handle their work.
The correct answer here is "cell membrane". Generally it makes sure that nothing enters or leaves the cell, except by its highly guarded "gates", such as ion channels, that let some particles through - but they're very picky about whom to let in!
The first time you get poison sumac, it usually takes a while to show up. If you have had it before, it takes around a day or two if you have had it before, so I'd say the answer to the question is no.
