Arrange the following structures in the order in which they vibrate when a sound wave enters the ear. eardrum (1) endolymph (2) ossicles (3) oval window (4) perilymph (5)

Eardrum→Ossicles→Oval window→Endolymph→Perilymph

Explanation:

The Ear is the organ of hearing and in mammals balance. In mammals the ear is often described as having three parts- The outer ear, the middle ear and the inner ear. the outer ear consist of the pinna and ear canal. The middle ear include the lymphatic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contain structures which are key to several senses: The semi circular canal which enable balance and eye tracking when moving. The Utricle and saccule which enable balance when stationary and the cochlea which enable hearing.

this would be a math

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
