Which are repeated, cyclic behavior patterns related to external stimuli? check all that apply. a) eating b) panting c) hibernating d) shivering e) migrating

Option 'C and 'E' are correct.

Explanation:

Hibernating and migrating are repeated, cyclic behavior patterns related to external stimuli.

Because hibernation is a behavior of yearly cycle.

It is a state when a body of animal start processing slower as compared to before because there is fall in their body temperature.

Similarly migration occurs when climate of particular region becomes uncomfortable for some species , they migrate from there. Like birds, when they do not get water because of hotness or dryness in the weather, they all migrate to the place for enough water.

Hence, option 'C and 'E' are correct.

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
