Let 51 be the region bounded by y x 2 , y 0, and x b, where b . 0. Let 52 be the region bounded by y x 2 , x 0, and y b2 . (a) Is there a value of b such that 51 and 52 have the same area? (b) Is there a value of b such that 51 sweeps out the same volume when rotated about the x-axis and the y-axis? (c) Is there a value of b such that 51 and 52 sweep out the same volume when rotated about the x-axis? (d) Is there a value of b such that 51 and 52 sweep out the same volume when rotated about the y-axis?

Lecture Notes March 9 , 2016 Reproduction and Development Anatomy and Physiology o Gametogenesis- the production of gametes Spermatogenesis- production of sperm- in the testes located in a sack like structure called the scrotum- occurs continuously throughout a male’s reproductive life Testes have two functional components o Seminiferous tubules- where the sperm is produced o Interstitial Cells- secrete the male sex hormone- testosterone During spermatogenesis the cells lining the seminiferous tubules are
