Which of these best describes the difference between a closed and open system and the total energy in the system.
A) Since energy is always conserved, the total energy in both systems remains the same.
B) In a closed system the amount of energy remains the same. In an open system, energy is always released.
C) In a closed system the amount of energy remains the same. In an open system, energy is always absorbed.
D) In a closed system the amount of energy remains the same. In an open system, work is either done on or by the system changing the energy of the system.

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.

explanation:

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
