Answer: The correct option is D (Sensory hair cells)
Explanation:
The ear is one of the sense organs recognised in humans which helps in hearing and for balance maintenance. There are different parts of the ear which includes:
--> the outer ear,
--> the middle ear and
--> the inner ear.
The semicircular canals are made up of three interconnected tubes which are located in the inner part of the ear. It consists of sensory hair cells which vibrates in response to sound.
Sensory hair cells serves as receptors of both auditory and vestibular systems, therefore are necessary for hearing and balancing. These cells can become damaged due to loud noises and sometimes will die resulting in hearing loss.
Answer:
d. contains secretions from three different accessory glands
Explanation:
The semen is not only made up of sperm. It also consists of secretions coming from three accessory glands: <u>seminal vesicles, prostate gland and bulbourethral gland.</u>
The seminal vesicles secrete<em> proteins, citric acid, sugar, etc</em>. and this accounts for<u><em> 2/3 volume of the semen</em></u>. It has a white color that has a tinge of brown.
The prostate glad, on the other hand, secretes a fluid that accounts for <u><em>1/3 volume of the semen.</em></u> This contains the Prostate Specific Antigen (PSA) that thins the semen.
The bulbourethral gland is also known as<em> "Cowper's gland." </em>This produces a secretion that ensures the sperm's motility.
