Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Answer:
The fluid within the semicircular ducts of the inner ear, that is, endolymph moves when the head is tilted. The precise position of the stimulated cells relies upon the plane of movement with each vertical or horizontal plane being signified by distinct parts of its composition. The hair cells that transduce the signal into an electrical signal get stimulated due to the movement of fluid. The conduction of this signal takes place via the auditory nerve to the cochlear nucleus of the brainstem.
Within the inner ear cochlea, the stimulation of the hair cells or stereocilia takes place by endolymph, it is a fluid present in semicircular ducts. After stimulation, the hair cells mediate electric signals to the brain via the auditory nerve, these are the nerve bundles that carry signals of sound. The initial central auditory composition found in the brainstem is the Cochlea nucleus.
Answer:
The correct option is 'A'
The breezes are the pollinator of pine trees.
Explanation:
Pine tree belong under genus Pinus and family Pinaceae which are important for it's timber and wood pulp.
Pine trees are mostly monoecious as the male and femlae contain cones which is present on the same tree but few are sub dioecious with single sex.
As they lack flowers,so pollination is not done by bee or butterfly.But they mainly pollinate by breeze or wind.
Female cone require 1.5 to 3 years to gain maturity after pollination.
At the onset of maturity, the diameter of female cone is 3-60cm long
The factor that is responsible for the phenomenon of the blood group B being almost absent in Native Americans whose ancestors arrived in very small numbers about 10,000 years ago would be called the 'founder effect'.
