Which statements are true? Explain why or why not.1 In the small intestine, stem cells in the cryptsdivide asymmetrically to maintain the population of cellsthat make up the villi; after each division, one daughterremains a stem cell and the other begins to divide rapidlyto produce differentiated progeny.2 Stem cells, being stem cells, are by definition thesame in all tissues.3 Every tissue that can be renewed is renewed froma tissue-specific population of stem cells.4 Disturbance of the balance in the activities ofosteoblasts and osteoclasts in favor of osteoclasts cangive rise to the condition known as osteoporosis, the brit-tle-bone syndrome of the elderly.

a. Explain how you could use worms transformedwith myo-2::GFP to find mutations that disrupt thestructure of the pharynx. How would the presenceof the transgene facilitate the mutant screen?b. Nematodes homozygous for loss-of-function mutations in a gene called pha-4 have no detectablepharyngeal structures. How could you use myo2::GFP to determine if pha-4 is a master regulatory gene that directs development of the pharynxin a manner similar to the way Pax-6/eyeless controls eye development?
