An ulcerated stomach lining often repairs itself once the source of inflammation has been eliminated. how is this possible?

a.) the tissue lining the stomach is an epithelium and thus capable of repair and renewal.
b.) the parasympathetic innervation of the stomach wall stimulates constant repair and renewal.
c.) the mucosa consists of a particularly vascular epithelium that facilitates efficient repair and renewal.
d.) all of the listed responses are correct.

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.

d. the weight of the book

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
