Biology
1 answer:
ZanzabumX [31]3 years ago
4 0

Answer:

Structures that are still present but currently serve little to no purpose

Explanation:

<em>Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.</em>

Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the <u>caudal vertebrae</u> found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.

<u>Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.</u>

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.

NEED HELP QUICK! <br><br> Suggest some reasons why Neanderthals might have become extinct.
Goshia [24]
I THINK
Neanderthals are the closest extinct relatives of modern humans, and lived in Europe and Asia. Recent findings suggest that Neanderthals were closely related enough to interbreed with ancestors of modern humans— about 1.5 to 2.1 percent of the DNA of anyone outside Africa is Neanderthal in origin
