Problem 19.54. a martian couple has children until they have 2 males (sexes of children are independent). compute the expected number of children the couple will have if, on mars, males are: (a) half as likely as females. (b) just as likely as females. (c) twice as likely as females.

the answer is c.) there is a warm front in region a and a stationary front in region b.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

wegner's theory did not explain how the continents could move

explanation:

dna is a set of a gene held together by a chemical bond
