Regulation of transcription of a specific gene involves sequences very close to the start of transcription as well as sequences that are many base pairs away from the transcription start site. You are using these sequences to drive expression of luciferase and monitor gene expression after you delete or modify these sequences. You delete the sequences that are located many base pairs away from the start of transcription and find that luciferase activity increases. What type of regulator did you most likely delete?

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

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. weathering is the breaking down or dissolving of rocks and minerals on earths surface. once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.
