Suppose you cut your finger only slightly in what is known as a "paper cut." you observe that the cut hurts but it doesn't bleed. how would you interpret your observation?
a. nerve endings occur in epithelium but blood vessels do not.
b. the paper severed the skin, missing blood vessels, but hitting nerve endings.
c. very thin cuts never draw blood but do sever nerves.
d. you probably have some unknown condition related to blood clotting.
e. the paper had some factor that prevented the release of blood but not the sensation of pain.

Nerve endings occur in epithelium but blood vessels do not.

Explanation:

Epithelial layer:

Among four tissue types of the body epithelial layer is one of them. epithelial layer is present around surface of all organs including skin, reproductive, respiratory and digestive tracts. Epithelial cells lack vessels, it means that they do not contain any blood vessels, These cells receive nourishment through the process of diffusion of substances from the underlying connective tissue,

Nerve endings are present inside Epithelial tissue, so that they feel pain when ever something cuts these layer.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
