If the ima of a machine is 2 and the effort force is 50 newtons, then the force applied to the resistance is 48 n 50 n 25 n 100 n

IMA stands for ideal mechanical advantage, which is the theoretical force amplification factor on an ideal mechanical device free of friction, deformations, etc.

If the applied force (effort) is 50N, then the force applied to the resistance is multiplied by the IMA=2 to get 100N.

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:

object 2 because all the other ones are wrong
