Describe the differences in prokaryotic and eukaryotic cells. How have the characteristics of each kind of cell put limitations and provided opportunities for the survival and divergence of modern living things? Why might both cell types be considered equally successful? Make sure to consider both Domains of Prokaryotes.

Professional Training & Development the United States Army Nurse Corps to begin her career. After a brief stint of orientation and training, Lila was deployed to Germany for her first assignment. It was an uncertain time as World War II was underway and tensions were high. Lila was transferred to an Army Tent Hospital outside of Paris, France shortly after arriving in Germany. Work in a tent hospital, caring for war-related injuries was quite different than any training she had encountered in the past. Rations were in affect and even the most basic supplies, such as toilet paper, were in short supply. Cleanliness was always a concern in the field hospitals and strict regulations were followed in attempt to decrease infection. Lila continued her career as an Army nurse for eight more years until she got married. She never forgot the early years that formed history as well as her nursing career. (Learning Objectives 3, 5, 7)
