Answer and Explanation:
Working of ear is follows:
Stage 1 : Firstly, the ear collects compression waves from the surroundings.
These waves are collected by the outer ear and passes to the eardrum via the ear canal.
Stage 2 : The ear amplifies the compression waves when the waves enter the ear drum. It caused fluid in the inner ear for moving.
Stage 3 : The amplified waves stimulate the hair cells of the ear through the fluid in the inner ear. It causes hair cells to bend.
Stage 4 : The hair cells transmit nerve impulse to the brain by changing movement into electrical impulse.
Stage 5 : The brain interprets the nerve impulses as sound.
Answer is Outer ..inner.
The outer ear is composed of the earlobe (pinna) and ear canal. The earlobe collects sound (hence its characteristic shape) and directed it via the rea canal where it hits and vibrates the eardrum. The middle ear amplifies the sound and transmits it to the inner ear ( comprised of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages) that has mechanoreceptors that convert the mechanical action of the sound to a nerve impulse.
The electromagnetic spectrum consists of electromagnetic radiation of all possible wavelengths.
It ranges roughly from wavelengths of 1 fm (10⁻¹⁵ m, gamma rays) to those of 1 Mm (10⁸ m, super low frequency waves).
Visible light occurs in the 400 nm – 700 nm region of the electromagnetic spectrum.
The Active Tags
They have that name doe to that this tags are self-powered by using batery, giving them independence from the reader, because don't need its energy to work, this characteristic allows to work at distances that can reach about 100 meters, but they are also more expensive, bigger and heavier because of the batery and the transmitter
D is the old way.
A they have not done yet
B not even a thing
Stage 2 - The ear amplifies the compression waves.
Stage 3 - The amplified waves stimulate the hair cells of the ear.
Stage 4 - The hair cells transmit nerve impulses to the brain
Stage 5 -The brain interprets the nerve impulses.
Hope this helps!
