The white matter of the spinal cord contains:A. InterneuronsB. Sensory and motor nucleiC. Bundles of axons that share common origins, destinations, and functionsD. Bundles of dendrites that share common origins, destinations, and functionsE. Both axons and dendrites

d Option C.

Bundles of axons that share common origins, destinations and functions.

Explanation:

White matter is an important component of the spinal cord and brain that form the nervous system. It is composed of myelinated axons and they connect grey matter of the brain to each other and also carry nerve impulses or signals to the neurons. The white matter has myelin, a fatty substance that surrond the axon and this is provide electrical insulation.

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
