Sometimes a short circuit in an electrical wiring system can produce enough thermal energy to melt a wire. How much thermal energy must be transferred to a 20.0-g piece of copper wire to raise it from room temperature (25.0°C) to its melting temperature (1085.0°C)?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
