Answer:
A. when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons.
Explanation:
This is the mechanism of propagation and transmission of sound waves as action potential to from the ear to auditory centres in the brain. This mechanism takes place in the inner ear( organ of corti, supported by basilar membrane.There are group of receptors in the Endolymph, whicha are hair cells supported by the tectorial membrane,.The organ of Corti acts as transducers in the inner ear and converts the circular fluid motion to electrical signals as action potential, when the hair cells bends against the tectorial membrane as a results of vibration of the endolymph The causes depolarization, and therefore action potential.
The potential is transmitted to the auditory centres in the brain for sound perceptions.
The cell membrane of cells present in tubeworm is selectively permeable and they prevent minerals in the water from flowing it in the cell of tube worms. By doing this the cell membrane protects the cell from any osmotic damage. By selectively preventing these minerals it maintains the stable environment in the cell.
Answer:
An increase in the population of a species increases the chances of survival for that species. The species will be able to survive severe changes such as diseases and disasters. However, if the species moves into a new area, competition will increase for the species already in that area. The increased competition will negatively affect these other species.
