Large Area Listening Systems. Large area listening systems are the most popular of all hearing enhancement devices, and are used in theaters, movie houses, auditoriums and houses of worship. There are three basic types: FM radio, infra-red (IR) light and a looped wire around the room, called an induction loop.
The strings are called Phloem Bundles (pronounced flom). They are part of the system that carries nutrition to all parts of the banana.
A large banana contains 6.6 grams of fructose, while a small banana boasts 4.9 grams. Your body quickly absorbs the glucose in bananas but takes somewhat longer to absorb the fructose and other sugars. This means bananas provide quick, short-term energy.
