B. Antibodies are found in the antibiotic medicines that can be taken to help the body fight off infections that have occurred.

C. Antibodies identify and destroy foreign materials and pathogens by producing powerful chemicals that dissolve them, making them harmless.

D. Antibodies attach to the surface proteins of antigens, inactivating the pathogen or signaling other immune cells to destroy the
foreign protein material.

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

i'm guessing this is from edg enuity so the answers would be, from top to bottom,

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
