Which of the following does not occur during cleavage?A. Rapid DNA synthesisB. Cell growthC. Differential distribution of nutrients and information moleculesD. A rapid series of cell divisionsE. Formation of the blastula
Women sometimes develop benign tumors calledovarian teratomas or dermoid cysts in their ovaries.Such a tumor begins when a primary oocyte escapesfrom its prophase I arrest and finishes meiosis Iwithin the ovary. (Normally meiosis I does not finish until the primary oocyte is expelled from theovary upon ovulation.) The secondary oocyte thendevelops as if it were an embryo. Development isdisorganized, however, and results in a tumorcontaining differentiated diploid tissues, includingteeth, hair, bone, muscle, and nerve. If a dermoidcyst forms in a woman whose genotype is Aa, whatare the possible genotypes of the cyst, assuming norecombination?
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.
In Meiosis, the Chromosomes ReplicateOnce but the Nucleus Divides Twice why?

Mitosis differs from meiosis in the following ways EXCEPT:(a) Mitosis results in a full complement of chromosomesin two cells, whereas meiosis results in four cells havinghalf the number of chromosomes.(b) In mitosis, all chromosomes are replicated, whereas inmeiosis, only half are replicated.(c) Mitosis only occurs in somatic or body cells, whereasmeiosis occurs in production of gametes or sex cells.(d) None of the above.(e) a and c only
