Arocket has landed on planet x, which has half the radius of earth. an astronaut onboard the rocket weighs twice as much on planet x as on earth. if the escape velocity for the rocket taking off from earth is vo, then its escape velocity on planet x is (a) 210 (b) v2v0 c) vo (d) vo/2 (e) vo/4

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:

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

it would be c. predictability
