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.
Re: how do bananas rot? The short answer bananas rot like anything else. It's a rotten world around us, and that's not a political commentary. Decomposers, primarily fungi and bacteria, are a necessary part of ecosystems. Organisms produce metabolic wastes, they shed aged, used parts, and ultimately they die.
