As part of this interface, the UART also: 1  Converts the bytes it receives from the computer along parallel circuits into a single serial bit stream for outbound transmission. 2  On inbound transmission, converts the serial bit stream into the bytes that the computer handles.
Cell specialization is the process in which a generic cell develops  into a specific type of cell. This happens in response to specific  triggers from the body or the cell iâ¦tself. Three examples of  specialized cells are the sperm cell, the fat cell, and the white  blood cell.
Cell differentiation refers to the normal process by which a less specialized cell goes through development and maturation in order to become more distinct in terms of form and function. It is the process in which a cell changes into another cell type. During cell differentiation, the changes may include cell shape, cell size, membrane potential, metabolic activities, and responsiveness. These changes are brought about by modifications in gene expressions. An example of cell differentiation is the development of a single-celled zygote into a multicellular embryo that further develops into a more complex multisystem of distinct cell types of a fetus. The cell size, shape, polarity, metabolism and responsiveness to signals change dramatically such that a less specialized cell becomes more specialized and acquires a more specific role.
