If r1= {3i – 2j + 5k}m, r2 = {4i -5k)m, r3= {3i – 2j + 5k}m. Determine the magnitude and dierction of of (r = 2r1- r2+ 3r3).​

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:

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
