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.
Prior to ripening, bananas are rich in resistant starch. However, as the fruit yellows, the starch converts into sugar, giving bananas their signature sweet flavor. So the more yellow the fruit is, the less resistant starch it will have.
