This is true. Urea carries the bloodstream to your kidneys which then transport waste along with water to form urine.
Answer:
converts electrical energy to mechanical energy
Explanation:
<span>The part of the ear where sound wave compressions and
rarefactions cause the eardrum to vibrate is the middle ear. The 8th
nerve in the inner ear actually converts the mechanical energy to electrical
energy for transmitting to the brain. A membrane called the tympanic membrane
separates the middle ear from the outer ear. Whenever a sound reaches the ear,
it creates a sound wave that creates vibration in the eardrum. The pressure
when high pushes the membrane inwards while low pressure sound waves helps the
eardrum to come outwards. </span>
