The middle ear communicates with the: <u>nasopharynx through the auditory meatus.</u>
- Since it creates the most pronounced anatomic opening between the two compartments in both animals and humans, it has long been considered that the round window membrane serves as the main pathway of communication between the middle ear and perilymph.
- The middle ear interacts with the pharynx, adjusts to changes in pressure outside, and transfers vibrations from the eardrum to the inner ear.
- The small passageway, also known as the auditory tube or eustachian tube, that runs from the middle ear to the nasopharynx.
- Pressure is equalized on both sides of the tympanic membrane via the tube (eardrum).
- The inner ear membrane in the fenestra ovalis receives sound waves from the incus through the stapes.

Transpiration involves mainly the xylem cells which become active during absorption process by the roots. Transpiration is helpful to plants in many ways. It helps in sending out excessively absorbed water by plants. It helps in the development of the plant body.

Explanation:
A mineral is a solid, inorganic, naturally occurring, ordered arrangement of an element or compound that has a fairly specific composition.
The endomembrane system<span> is a group of cell membranes and organelles that are mutually interconnected, either by being directly continuous with one another or by sending one another </span>vesicles<span>—little spheres of membrane then can bud off from one membrane and fuse with another.
</span>The rough endoplasmic reticulum<span> (</span>rough ER<span>) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As the ribosomes attached to the rough ER make proteins, they feed the newly forming protein chains into the lumen.
</span>
The smooth endoplasmic reticulum<span> (</span>smooth ER) does not have ribosomes on its cytoplasmic face.<span>The smooth ER has a variety of functions, and its exact role may vary between cell types.
</span>
<span>One role of the smooth ER is to produce lipids, including phospholipids, cholesterol, and steroids.
