Stem cells in the seminiferous tubules that undergo mitosis or differentiate and become primary spermatocytes that enter meiosis: ___ Sperm develop from stem cells called: A. spermatogonia. B. primary spermatocytes. C. secondary spermatocytes. D. spermatids. E. spermatozoa. ...
Sperm develop from stem cells called: A. spermatogonia. B. primary spermatocytes. C. secondary spermatocytes. D. spermatids. E. spermatozoa. The prenatal stage of conception begins with - the maturation of the female ovum and its entry into the fallopian tube. - the entry...
Some cells are set up to become stem cells, which will then have the potential to develop into any type of cell in the body. And some cells in the fetus become primordial germ cells and eventually evolve into the cells of either sperm or eggs, which will allow this offspring to pass th...
Researchers have successfully created functional sperm cells from mouse stem cells in the laboratory, then implanted those cells into rodents' egg cells to produce healthy, fertile offspring. The breakthrough could be significant, with the potential to c
He said his team took stem cells derived from adult human skin cells, as well as others cultured in the lab, then reverted the cells to an early state with the potential to develop into different cell types. MORE: Places the U.S. Government Warns Not to Travel Right Now ...
This experiment is the first time artificial embryos have started to develop into fetal tissue in a uterus. Other groups have made artificial mouse embryos from stem cells but they haven’t successfully implanted or have only been able to form placental cells but not the other cell t...
Sperm develop from stem cells called: A. spermatogonia. B. primary spermatocytes. C. secondary spermatocytes. D. spermatids. E. spermatozoa. Cells that are formed during spermatogenesis by the first meiosis are called: a) spermatids. b) secondary spermatocytes. c) spermatogonia. d) primary spe...
Thus, the application of a native protein with a physiologically relevant activity, that is, to trigger egg activation, following the fusion process occurring between the somatic cell and the egg cell, would enhance the success rate of fused cells in proceeding to develop further. Stem cells ...
Spermatogenesis is a process of differentiation that happens in the seminiferous epithelium located in the testis of male species to create spermatozoa. This process is sustained by spermatogonial stem cells, tissue-specific stem cells.Answer and Explanation: ...
egg and sperm), the cells are called spermatozoa. Spermatozoa have 23 chromosomes, which is half the amount of chromosomes found in a normal non-reproductive cell. The spermatozoa are then sent to the epididymis where they are stored to mature. It is inside theepididymisthat sperm develop the...
