1.) A student recently told me that both she and her brother have blue eyes (bb), and that both of her parents are brown-eyed. Using a Punnett square, list the genotypes and phenotypes showing how it’s possible for this to happen. Show punet square work please and thank you!!!

Unfortunately I can't draw the square but the parents are both Bb as this is the only possible genotype that can give bb as genotype in the crossing

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'd say that the moon rock is about 2.2 billion years old.
