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.
Some ICBMs are also capable of breaking up into multiple bomblets for more widespread damage. Since an ICBM has a long range, the device can be used to attack a nation from a safe distance, an appealing method of waging war for many nations. Ballistic missiles can also be launched from submarines and some ships.
