When PCs all had parallel bus architecture, the UART's purpose was to convert bytes from the PC's parallel bus to a serial bit-stream. The cable going out of the serial port is serial and has only one wire for each direction of flow. The serial port sends out a stream of bits, one bit at a time.
Three primary characteristics of connective tissue have been described as: Have a rich supply of blood vessels. Composed of many types of cells. Great deal of noncellular, â¦ nonliving material (matrix) between the cells of connective tissue.oose Connective Tissue consists of a lot of ground substance and it has all 3 types of protein fibers. Dense Connective Tissue on the other hand has little ground substance, â¦ few cells, and although it has most protein fibers it mainly consists of collagen fibers.
Answers. Best Answer: Structure of Connective Tissue The essential characteristic that separates connective tissue from the other three tissue types is the presence of an abundant amount of extracellular matrix or material between its cells.The extracellular matrix has three major components: Protein fibers (ie.ollagen, reticular & elastin) Ground substances consisting of nonfibrous proteins and other materials Fluid Classification of Connective Tissue The extracellular matrix is the basis for the classification of connective tissue into the three following subgroups: Matrix with mainly protein fibers (ie.
