Francis gently combed through his hair and four hairs came out. which is most likely the age of the four hairs? 6 months 10 months 2 years 4 years

The correct answer is 4 years.

The falling of hair is a common factor but there are certain reasons because of which the hair fall. These reasons can be genetic factors, pollution or unhealthy diet else lack of sleep can be one of the reasons. Naturally, hairs are anagen phase for two to four years and then the phase is changed into telogen and in this phase it rests for about two to four months and then the falls. This place is occupied by the new, growing hair.

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
