What is the primary function of carbohydrates attached to the exterior of cell membranes?
identification of the cell
flexibility of the membrane
strengthening the membrane
channels through membrane

The correct option is : a. Identification of the cell

Explanation:

The cell membrane, also called plasma membrane, is a semi-permeable membrane surrounding the cytoplasm of the cell, that protects and separates the interior of the cells from the external environment.

The carbohydrate layer of the cell membrane is known as the glycocalyx. In eukaryotes, the carbohydrates present on the surface of the cell membrane play a important role in the cell-cell recognition and share information.

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
