To generate heat endotherms convert the food they eat into energy through the process called metabolism. Most of the food that the endotherms eat is converted into fuel to maintain a constant body temperature. Endotherms need to eat more food than ectoderms of the same size to maintain their constant body temperature.

-Adult skin cells have gone through differentiation and cannot become another type of cell. Same case applies to the skin cells, they have already undergone differentiation;
-Similarity; The cells that are taken from the same person would have the same DNA.
-Difference; The skin cells and the adult stem cells have already gone through differentiation, whereas embryonic stem cells have not. The different genes that the types of cells have are turned on and off causing the differences.
