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.
Classifying ballistic missiles by range is done mostly for convenience, in principle there is very little difference between a low-performance ICBM and a high-performance IRBM. The range definition used here is used within the U.S. Missile Defense Agency. Some other sources include an additional category, the long-range ballistic missile (LRBM), to describe missiles with a range between IRBMs and true ICBMs.
