The cell membrane is selectively permeable. It only lets things in or out.
astra-53 [7]3 years ago
4 0

Answer:

semi permeable

Explanation:

Cell membranes are semipermeable, which means molecules can move through them. Yes, it can be both. Semipermeable suggests that the membrane allows some substances to pass through, but not all, and this is generally by DIFFUSION. ... Permissible molecules are selected for the best survival of the cell and therefore, plasma membrane is selectively permeable.

The outer hair cells change length in response to basilar membrane motion. What does that accomplish?
olga nikolaevna [1]

Outer hair cells change their axial dimensions in response to electrical stimulation.

What is basilar membrane motion?

Hair cell stereocilia move as a result of the basilar membrane's movement. The tectorial membrane and the hair cells, which are connected to the basilar membrane, move along with it when it moves, and the stereocilia bend in response to the relative motion of the tectorial membrane.

The hair cells that are linked to the auditory nerve fibers are stimulated by the basilar membrane's movement. While the outside hair cells actively affect the basilar membrane's vibrations, the inner hair cells convert hydromechanical vibration into action potentials.

With each sound cycle, the intracellular voltage of the outer hair cells varies, causing them to lengthen and contract. This increases the organ of Corti's vibration, enabling exceptionally high hearing sensitivity and frequency selectivity.
