Answer:
The correct answer will be- seminiferous tubules of scrotum.
Explanation:
Spermatogenesis is the process of formation of male gametes or sperms. The process begins when spermatogonia in seminiferous tubules divide by mitosis and meiosis I and becomes primary spermatocytes and meiosis II and form secondary spermatocyte.
The secondary spermatocyte differentiates into sperms where the large Sertoli cells nourish the immature sperm. The sperms get stored in the epididymis where also they get nourished.
Thus, seminiferous tubules of the scrotum are the correct answer.
The relative rates of diffusion of these molecules from the fastest to the slowest is; Estrogen, propanol, alanine, sodium
Phospholipid bilayer consists of two layers of phospholipids, with a hydrophobic, or water hating, interior and a hydrophilic, or water loving, exterior. This bilayer gives the cell membrane a property to allow selective movement of molecules in and out of the cell. Ions and larger polar molecules cannot pass through the lipid bilayer, passing of the molecule through the membrane depends on its size and its electrical nature.
