They are water soluble and poured down the drain with the water.
They should be carbohydrates, fats (lipids) and protein. they are labelled as primary food substances and they're essential to life. they can provide energy and raw material for life processing. although mineral ions and vitamin are important too, but they only need a small amount.
I don't know what your key vocabulary is..., but this is your answer!!
When the amplitude of a sound wave increases, the intensity of the sound increases therefore the sound seems louder but does not change the pitch.
Therefore, if you increase the amplitude of the sound wave(s) of your cell phone ring, it will still sound the same yet louder.
For example, think of when you are increasing the volume on your phone... You are increasing the amplitude of your phone's speaker sound wave and whatever you were tuning in to would sound louder but would stay the same. It wouldn't go from a robot to a kitty sound now. Same concept happens when you decrease the volume on your phone yet this time you are decreasing the amplitude of a sound wave(s) and it gets softer.
