The 1st law of thermodynamics is a statement about (a) temperatures scales (b) whether a process can proceed in a specific manner (c) the efficiency of a system (d) energy conservation (e) none of the above

Energy conservation.

Explanation:

The 1st Law of Thermodynamics is a statement about energy conservation. It states that , which means that if we substract the work W done by the system to the heat Q given to the system we get the change in the internal energy , so any excess in energy given to the system appears as internal energy, stating that energy is conserved.

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.
