MODELS OF ADOPTION CYCLE The Technology Adoption Lifecycle The technology adoption lifecycle model describes the adoption or acceptance of a new product or innovation‚ according to the demographic and psychological characteristics of defined adopter groups. The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve." The model indicates that the first group of people to use a new product is called "innovators‚" followed by "early adopters." Next

Spermatogenesis Spermatogenesis is the production of the male gametes (reproductive or sex cell) otherwise known as sperm. The production of sperm takes place in the seminiferous tubules within the testes and are formed from cells by a type of cell division called mitosis and then meiosis. This process begins at puberty. Spermatogonia cells are made by mitotic division of the primordial germ cell. Mitotic cell division produces diploid cells that are identical to the Parent cell with 46 chromosomes
