Hey you! Here's your answer:
1) Scientists discovered ways to derive embryonic stem cells in 1981, more than 30 years ago.
2) Canadian Scientists Dr. James Till and Ernest McCulloch, who did pioneering studies in stem cell research, were the first to discover stem cells.
3) Thousands of experiments and studies have already been conducted on stem cells and research.
I Really Hope This Helped You! :)

The right answer is d. sugar molecules move outside of the membrane.
The simple diffusion is the diffusion through the plasma membrane (in the direction of the strong concentrations towards the weak concentrations, until equilibrium concentrations on both sides of the membrane). In the case that we have, the most concentrated compartment in glucose (that is inside the cell) will let it escape and go to the extracellular compartments until reaching equal concentrations between the two compartments.
Greater flexibility and mobility to facilitate movement and the segments become joined into larger body regions, with internal structures also combined.
