Helppp me :( The continuum below shows the development of the human embryo into an adult and the types of stem cells involved.

a) List the four types of stem cells, give an exmple of each type, and explain how much each type can differentiate.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

if you know your abc's you should be able to get your answer or just use google
