Starch and fiber are also considered complex carbohydrates but fiber can not be digested or used for energy. Starch is probably the most important energy source in an athleteâs diet because it is broken down and stored as glycogen. Foods high in starch include whole grain breads, cereals, pasta, and grains.
Conventionally, ICBM is a term used only for land-based systems, in order to differentiate them from submarine-launched ballistic missiles (SLBMs), which can also have an intercontinental range. As of this writing, only three countries have operational ICBM systems: the United States, Russia, and China.
A ballistic missile is powered early in its flight and then follows a non-powered trajectory to its target. During the Cold War, both the United States and the Soviet Union developed inter-continental ballistic missiles, known by the acronym ICBM, that were capable of reaching any target in each other's territory. ICBMs could deliver nuclear weapons in a manner that was virtually immune to defensive measures.
