The "once a cesarean, always a cesarean" rule originated when the classical uterine incision was made vertically; the resulting scar was weak and had a risk of rupturing in subsequent deliveries. Today, the incision is almost always made horizontally across the lower end

Cells and Cell Theory
Cells and Cell Theory What advantages does small size give to a cell? Many cellular processes occur by diffusion, which is efficient over short distances, but less efficient over long distances. Since all materials going in and out of a cell must pass through the plasma membrane, the greater the surface area of this membrane, the faster a given quantity of molecules can pass through. Smaller cells have a much greater surface-to-volume ratio than larger

Cellular Reproduction
Cellular Reproduction Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce, that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process, whether asexual or sexual always involves an exchange

Centripetal Forces
While the bob is moving in the circular motion, the centripetal force that is provided is the spring. The spring causes the bob to get pulled inward and while it is being pulled inward while being rotated it provides a centripetal force. If this force was suddenly removed, the Bob would still have a centripetal force due to the rope in which it hangs from causing the inward force to keep moving in a circle.
