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.
They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues.
